HYBRIDIZATION Hybridization is the mixing together of "atomic
... Hybridization is the mixing together of "atomic orbitals" (i.e., s-, p-) to form new, hybridized atomic orbitals. These new, hybridized, atomic orbitals overlap to form σ and π bonds. Carbon, oxygen and nitrogen valence atomic orbitals hybridize to form sp3, sp2 or sp hybridized orbitals. For neutra ...
