How Chemical Bonds Are Formed.

• Introduction

A chemical bond is the force, which holds two or more than two atoms or ions together to form a large variety of com[pound. The forces which are responsible for such bonding and the shapes of molecules formed are as a result of chemical combination. The theory of chemical bonding has been a major problem of modern chemistry. Lets take a look on the nature of the chemical bonds formed between the atoms.

• Cause of Chemical Combination 

It has been observed that the chemical reactivities of the elements, depend upon their characteristic electronic configurations. The noble gases with inert  electronic configuration shows little tendency to react chemically. There are just few stable compounds, formed by these elements like xenon trioxide. A noble gas dose not react with other noble gas. Thus these gases are most stable of all elements. Let us, see why noble gases are most stable. This can be explained on the basis of their special electronic configuration, their outer most s and p orbitals are completely filled. All other elements, combine with one another, due to an inherent tendency to stabilized themselves. They get their stabilization by losing, gaining or sharing  electrons to attain nearest noble gas configuration. The tendency of an atom to attain maximum of eight electrons in the valence shell is known as octet rule. Lets examine some images which helps us to understand nature of bonding.
