Atomic orbitals can be combined and reshaped –much like dough– to make other orbitals of different shapes and properties. There are two basic types of orbitals that can result from such processes. They are:
1. HYBRID ORBITALS. They result from combinations of orbitals within a given atom, either prior to or as bonding with another atom takes place.
2. MOLECULAR ORBITALS. They result from combinations of orbitals between atoms as bonding takes place to form molecules.
