WHAT IS POLYMORPHISM?

Hybridisation

When bonds are formed between atoms in the formation of molecules, there is a change in the nature of the atomic orbitals in each atom. Effectively, new molecular orbitals are formed, and the electrons in these orbitals are those of the molecule as a whole. The alteration of the structure of the atomic orbitals is called hydridisation, as it involves combining a number of orbitals to create an equal number of new orbitals, where each of the new hybrid orbitals have properties which are an average of those of the orbitals from which they were created.
