Orbital hybridisation - In chemistry, hybridisation is the mixing of atomic orbitals to form new orbitals suitable for bonding. Hybridisation is an integral part of the valence shell electron-pair repulsion (VSEPR) theory as well as a quantum mechanical model for orbital electrons to describe groups 2,3,4 of the periodic families of elements whose electron orbital clouds fuse into one hybrid orbital. Groups 1,5,6 and 7 in the period table do not hybridise. ...
