6.1 Causes of Chemical Combination

Except for noble gases, no other element exists as independent atom in ordinary conditions. Most of these atoms exist as molecules.

The attractive force which holds together the constituent particles (atoms, ions, or molecules) in a chemical species is known as chemical bond.

The tendency of elements to combine with one another is directly related to valency or valence of the element. Valency depends on the electronic configuration. W. Kossel and G.N.Lewis  made important contributions in the development of theories of chemical bonding.
