When chemists talk about "bonding," it is not code for some Cold War spy mission to find James Bond. It refers to something way cooler. Okay, maybe just slightly cooler. Bonding is the term used to talk about how atoms are connected to one another. It has nothing to do with James Bond. Luckily, it has everything to do though with crazy reactions.

Some atoms are attracted to one another while others are repelled by one another. This behavior isn't too dissimilar from what we see with individual people, except atoms are a bit more extreme. When some atoms are attracted to each other, they are really attracted.

We aren't just talking about partners for life; we are talking partners for hundreds, thousands, sometimes, millions of years or more. Bond strength is an indicator of how great the attraction is between two atoms. There are several types of bonds in chemistry. For now though, let's just concern ourselves with the big picture. All types of bonds involve these little negatively charged particles called electrons.

Atoms that have too few electrons want more. Atoms with too many electrons want to get rid of some. Some atoms like to share. Others are pretty electron-greedy. Did we mention that atoms are kind of like people? If that's the case, electrons are chemical currency. When electron transactions take place, something really cool happens.

Chemical reactions are a result of bonding changes. During a chemical reaction, the atoms bonded together in the beginning rearrange in new ways. The result is different chemicals and at times, a release of energy. Check out this smorgasbord of cool chemical reactions.

There's one last thing to discuss. We would be remiss if we didn't introduce a chemical equation. Chemistry has its own language. Here is an example of a chemical equation that a chemist uses to describe a particular reaction:

Fe + S → FeS

To the left of the arrow, chemists list the reactants. These are the chemicals that we start with. When they are added together, a reaction occurs. Think: ka-boom. To the right of the arrow, chemists list the products. These are the chemicals that are made as a result of the chemical reaction.

The arrow serves as an indication of a chemical transformation. We mix together a little bit of iron (Fe), some sulfur (S), and voilà. We now have iron sulfide. Chemists represent this chemical compound as FeS.

Note: Subscripts are absent from this chemical compound. When subscripts are absent, we will always just assume one atom is needed to make the chemical compound. In the case of FeS, one atom of iron comes together with one atom of sulfur. Now, back to the equation.

Notice that the elements that are present on the left hand side of the chemical equation are the same as the elements present on the right hand side of the equation. Magic? No. Important? Yes. In chemical reactions, the elements never change. Instead, the bonding situation changes. As a result, there is a new chemical compound.

Introduction

Atomic Structure

To understand how elements are combined to form compounds, it is necessary to understand the structure of atoms. Atoms consist mainly of electrically charged particles called electrons and protons. Each electron has negative charge and each proton has a positive charge. Neutrons, which are also present in atoms, have no charge. Normally, an atom contains as many electrons as protons. The negative charges and the positive charges balance each other and the atom is neutral (uncharged). If the balance between electrons and protons is upset, the atom becomes an electrically charged unit called anion. An atom becomes positive ion if it loses one or more electrons and they are called cation. For example, when a hydrogen atom loses its single electron. It becomes a positive hydrogen ion (H+). A negative chlorine ion (Cl-) is a chlorine atom with one additional electron.

Electrons revolve in various distances from the nucleus of an atom. The path of the electron forms a series of shells with the nucleus at the center. Each succeeding shell is farther from the nucleus from the one below it. Scientist has found that each shell can contain no more than a certain number of electrons. The first shell holds no more than 2 electrons. The second can hold 8; the third, no more than 18 and so on. Most interactions among atoms take place in the outermost shell of each atom. The number of each electron in this shell determines how an atom combines with other atoms to form compounds. When atoms combine they gain, lose or share electrons in such a way that the outer shells become chemically complete.

Valence is the property related to the electrons in an atom’s outer shell. The valence of an element is the number of electrons the elements gain or loses when it forms compounds with other elements. Electrons in the outermost shell are called valence electron.

Chemical bonding

What is chemical bonding?

Atoms, in a sense, are tied together to form molecules. The atoms of molecules are linked together through a reaction known as chemical bonding. A chemical bond is a force that holds atom together. How do atoms combine? What are the forces that bind them? These questions are fundamental in the study of chemistry since a chemical reaction is essentially an alteration of chemical bonds. An important clue to the understanding of the driving force for chemical bonding was the discovery of the noble gases and their apparently inert chemical behavior. Elements tend to attain this configuration of completely filled outer shells in order to gain stability.

The transfer or sharing of electrons of the atoms in a compound forms a linkage between them which chemists call the chemical bond. There are two types of chemical bonds, (1) ionic bond and (2) covalent bond.

Octet Rule

In order to acquire an inert gas configuration, there is a need for 8 electrons to occupy the s p distribution in the highest energy level of an atom.

Consider the individual elements Na and Cl. Sodium has the electronic configuration:

Na = 1s2 2s2 2p6 3s1

And its outer shell configuration is 3s

Cl = 1s2 2s2 2p6 3s2 3p5

And its outer shell configuration is 3p5

How could Na and Cl attain the outer-shell octet?

There are three possible ways for any atom to take in pursuit of an octet:

1. Electrons could be given up to some other atoms or group of atoms.

2. Electrons could be gained from some other atoms.

3. Electrons could be shared between two atoms.

The three choices are depicted in the figure below. Apply these choices to sodium and chlorine.

Let us consider first Sodium and apply each of these choices:

In the first choice, if the 3s1 is lost, the second shell becomes the outer-shell, with a configuration of 2s2 2p6, an outer-shell octet. The sodium now has 11 protons and 10 electrons, giving it a net charge of +1 (Na +1).

For the second possibility, a total of 7 electrons would have to be gained to produce the outer-shell octet3s2 3p6. Each time an electron is gained, the Na atom acquires one unit of negative electrical charge, therefore, a gain of seven electrons produces a net charge of -7, which is noted as Na -7.

If the third choice is taken and electrons are shared, Sodium could provide one electron (the 3s1) and the other atom(s), would have to provide a total of seven more.

Now which of the three possibilities will Na choose?

In general, atoms will follow the "course of action" which results in the most stable situation - the lowest energy state. It is difficult for any atom to find other atoms, which will give up a total of 7 electrons.

Also, the Na -7 is not stable, because the 11 protons of Sodium could not be able to exert a strong force of attraction to hold on to the 18 electrons. And in an attempt to share electrons, Sodium will have the trouble finding atoms, which have the trouble finding atoms, which must provide the majority of electrons shared. Figure 6-2 illustrates these points.

Therefore, the best possibility for Na to achieve an outer-shell octet is the loss of one electron to form Na +1.

Apply the same type of reasoning to chlorine atom. Because there are seven electrons in the outer energy level, Chlorine needs only one electron to complete an octet in the third energy level. Therefore, the possibility that Cl will follow most likely is by gaining an electron from some other atom, forming Cl-1. Since an electron has been gained, the configuration of Chlorine ion is:

Cl - 1s2 2s2 2p6 3s2 3p6

Ionic or electrovalent bond

An ionic bond is formed in a compound when the electrons from the outermost shell of an atom are actually transferred to the outermost shell of the combining atom.

This transfer occurs from one who has a lesser attraction to one who has a greater attraction for electrons. After the transfer has occurred, the atom, which gained the electron(s), now contains more electrons than protons thus, it is negatively charge.

That one from which the electron(s) have been removed has more protons than electrons and is therefore positively charged. These charged particles are called ions. A positively charged ion is called cation, and a negatively charged ion is called an anion. Since these ions have opposite charges, there is an attractive force between them. This attractive force constitutes the ionic bond otherwise called electrovalent bond. However, the ions are free and exist as separate particles whether they are in dissolved or solid form. A typical example of an ionic or electrovalent bond is the bond formed between sodium and chlorine atoms when they enter into chemical combination.

An illustration of Ionic Bonding

An ionic bond is formed in a compound when the electrons from the outermost shell of an atom are actually transferred to the outermost shell of the combining atom.

Illustrations of covalent bonds

The chemical bond in which two atoms share a pair of electron and form molecules is called covalent bond.

Covalent bonds are classified into non polar and polar covalent bonds.

Covalent bond

Some compounds are formed when electrons are shared between two atoms to fill up the incomplete outer shell of both in order to attain the stable configuration of an inert gas. This usually occurs when reaction takes place between atoms of Group IV, V, and VII. The chemical bond in which two atoms share a pair of electron and form molecules is called covalent bond. The atoms of covalent compounds are not free like those in ionic compounds. They are tightly linked to one another by the covalent bond. Hence each independent particle is a combination of the atoms.

What is the nature of the bond formed between H and F in the molecule HF?

The electron configurations:

Hydrogen (H) 1s1

Fluorine (F) 1s2 2s2 2p5

Make clear that H needs one electron to attain a stable 1s2 outer shell configuration, and F needs one electron to attain an octet. Since neither can easily lose electron, sharing occurs and a covalent bond is formed.

Covalent bond is the bond formed in which two atoms share a pair of electrons and form molecules. The bond that results whenever unequal sharing occurs is called polar covalent bond while equal sharing of electrons is called non polar covalent bond.

Chemical bonds are produced when the outer-shell electrons are either transferred or shared from one atom to another. The formation of chemical bonds usually enables an atom to acquire a chemically stable outer-shell consisting of an octet of electrons. There are two types of chemical bonds. (1) Ionic bond, in which electrons are actually transferred from the outer-shell of one atom to the second atom. The resulting particles are ion – atom or groups of atoms with an unbalance electrostatic charge. (2) Covalent bond, in which two atoms share a pair of electrons and form molecules. The bond that results whenever unequal sharing occurs is called a polar covalent bond. Equal sharing of electrons is called non polar covalent bond.

A chemical bond is an attraction between atoms due to sharing of electrons between atoms or a complete transfer of electrons from one atom to another. There are three types of chemical bonds. They are ionic, covalent, and polar covalent. Almost everything a person sees or touches in daily life—the air we breathe, the food we eat, the clothes we wear, and so on—is the result of a chemical bond, or, more accurately, many chemical bonds. As a future educator, the word or term "bond" means a lot. In a classroom setting, it is important to have a bonding between the teacher and the learners for them to feel the belongingness inside the classroom. Teachers cannot help the student in his or her concerns if they didn't established a bond between them. So, it is really important to have a bonding for the teachers to touch their students' lives forever.

Villaroman, Nikki D.C. BEEd III on February 24, 2017:

Chemical compounds are formed by the joining of two or more atoms. A stable compound occurs when the total energy of the combination has lower energy than the separated atoms. The bound state implies a net attractive force between the atoms ... a chemical bond. The two extreme cases of chemical bonds are:

Covalent bond: bond in which one or more pairs of electrons are shared by two atoms.

Ionic bond: bond in which one or more electrons from one atom are removed and attached to another atom, resulting in positive and negative ions which attract each other.

Other types of bonds include metallic bonds and hydrogen bonding. The attractive forces between molecules in a liquid can be characterized as van der Waals bonds.

A chemical bond is a lasting attraction between atoms that enables the formation of chemical compounds. The bond may result from the electrostatic force of attraction between atoms with opposite charges, or through the sharing of electrons as in the covalent bonds. Chemical bonding, any of the interactions that account for the association of atoms into molecules, ions, crystals, and other stable species that make up the familiar substances of the everyday world. When atoms approach one another, their nuclei and electrons interact and tend to distribute themselves in space in such a way that the total energy is lower than it would be in any alternative arrangement. If the total energy of a group of atoms is lower than the sum of the energies of the component atoms, they then bond together and the energy lowering is the bonding energy. Chemical Bonds are attractions between two or more atoms, which allow them to create chemical substances/compounds These bonds are formed by the electromagnetic forces between the

BEED-II BSC206B (Inorganic Chemistry/ TF/ 12:30-2:00)

Chemical bond refers to the forces holding atoms together to form molecules and solids. This force is of electric nature, and the attraction between electrons of one atom to the nucleus of another atom contribute to what is known as chemical bonds. Although electrons of one atom repel electrons of another, but the repulsion is relatively small. So is the repulsion between atomic nuclei.

The attraction force between ions are called ionic bonding. Metals such as sodium, copper, gold, iron etc. have special properties such as being good electric conductors. Electrons in these solids move freely throughout the entire solid, and the forces holding atoms together are called metallic bonds. To some extend, metals are ions submerged is electrons.

When atoms approach one another, their nuclei and electronsinteract and tend to distribute themselves in space in such a way that the total energy is lower than it would be in any alternative arrangement. If the total energy of a group of atoms is lower than the sum of the energies of the component atoms, they then bond together and the energy lowering is the bonding energy. As a future teacher we must know how to bond our objectives for our students learning will be more realized in an easiest ways.

A chemical bond is an attraction between atoms that allows the formation of chemical substances that contain two or more atoms. The bond is caused by the electrostatic force of attraction between opposite charges, either between electrons and nuclei, or as the result of a dipole attraction. Since opposite charges attract via a simple electromagnetic force, the negatively charged electrons that are orbiting the nucleus and the positively charged protons in the nucleus attract each other. An electron positioned between two nuclei will be attracted to both of them, and the nuclei will be attracted toward electrons in this position. This attraction constitutes the chemical bond. Due to the matter wave nature of electrons and their smaller mass, they must occupy a much larger amount of volume compared with the nuclei, and this volume occupied by the electrons keeps the atomic nuclei relatively far apart, as compared with the size of the nuclei themselves. This phenomenon limits the distance between nuclei and atoms in a bond.

Chemical bonding is the physical process responsible for the attractive interactions between atoms and molecules, and that confers stability to diatomic and polyatomic chemical compounds.

Phoebe Sp on March 05, 2015:

Strong chemical bonding is associated with the sharing or transfer of electrons between the participating atoms. The atoms in molecules, crystals, metals and diatomic gases indeed most of the physical environment around us are held together by chemical bonds, which dictate the structure and the bulk properties of matter.

Chemical bonding has a great role in our field. Our industry, Hospitality Management relies on people. So having this knowledge will also lead us to better relation with our costumers. Also, in Food and Beverage Department we mixed or the ingredients that we used is compatible or not to each other. That’s why we need to study Chemical Bonding to know how the things join together or how things connected to each other.

Patrisha Anne D.Vanguardia from San Ildefonso,Bulacan on March 04, 2015:

17 Flores, AJ BUHM

For me, Chemical bonds are what keep the atoms in a molecule together, without them you won't exist, the tables and chairs and anything visible would no exist. No compounds would exist but because of the way atoms are held together these bonds exist. It is impossible for them not to make bonds with their current structure. chemical bonds are necessary in order to perform most of life's processes. Many biochemical pathways important to life involve the breaking and joining of numerous chemical bonds. The world is generally not composed of isolated atoms; rather, atoms bond to one another to form molecules and hence chemical compounds. Not all chemical bonds are created equal: some are weak, and some very strong, a difference that depends primarily on the interactions of electrons between atoms.

Chemical Bonding Is Related On Hm Student. On How can Communicate To Different People We Are Facing And How Food /beverage Different Kind Of Spices That we Mix Together

AngelicaBSHM1-1 on February 01, 2015:

The relevance of this subject to our field of study is for us to know that cooking is science, especially chemistry. For us to know that whatever we are cooking or whatever the way we cooking, it is science. As your food touches the fire, the food conduct heat and it undergoes a chemical change process. Some particles of the food that we are cooking are disappearing while some are going into your food making it different in molecular structures. Just like when you grill your barbecue, the barbecue will be cooked because of the fire of course, and when you forgot that your are grilling barbecue, looked what you've had. "COAL", because your burned your barbecue it turns to a bunch of carbon stuffs.

This is not only in relevant on our field but for all. Studying and knowing this, is very useful in a way that we interact with other people. Bonding typically refers to the process of attachment that develops between romantic partners, close friends, or parents and children. It would very interesting for us to know about this because these are not only used for chemicals and experiments with different processes but also on how we deal with other people specially for us who are looking forward to be professionals someday this can be used in business.

For me, it is also important for us to know what chemical bonding is. Because when we work in a hotel, restaurant, cruiselines we will encounter different types of guest and with that we must know how to treat everyone with respect so that we will have harmonious relationship as well as with our co staff we must learn how to respect each other, learn how to share what's on your mind, learn how to give what is right and in end you and your co staff will be successful just like in atoms if some atoms need to become stable they must find another atom that is fit for them to become stable. We must learn how to give and share because in Hospitality Industry it's a must and i must say everyone must have this capability to share and give to others.
