Chemical bonds an introduction

This attraction is known as an ionic bond. Attainment of stable configuration[ edit ] As said above, the atoms combine with each other only when there is a decrease in stored potential energy. Therefore, the ionic compounds dissociate easily in water, and the metallic properties of the compound allow conductivity of the solution.

This means that the two shared electrons are closer to one of the atoms than the other, creating an imbalance of charge. The development of quantum mechanics in the 's and 's has revolutionized our understanding of the chemical bond.

chemical bonding questions

However, the bonds between C and N atoms in cyanide are of the covalent type, so that each carbon is strongly bound to just one nitrogen, to which it is physically much closer than it is to other carbons or nitrogens in a sodium cyanide crystal.

Bond lengths give us valuable structural information about the positions of the atomic nuclei.

chemical bond examples

It has allowed chemists to advance from the simple picture that covalent and ionic bonding affords to a more complex model based on molecular orbital theory. An example is nitrogen. Covalent Bonds Chemical bonds are the forces of attraction that tie atoms together.

On the other hand, longer-range covalent interactions can be quite strong, making their compounds very durable.
