Hybrid orbitals can be occupied by electrons in isolated atoms all have the same shapes and energies when formed around a single central atom have similar shapes to s, p, and d orbitals in isolated atoms create sigma and and n bonds pi
Valence bond theory describes covalent bonds as the overlap of half-filled orbitals with electron pairs localized between two bonded atoms uses a combination of atomic orbitals to create molecular orbitals with electrons delocalized throughout the entire molecule creates bonding and anti -bonding interactions based on which orbitals are filled correctly predicts paramagnetism in molecules
