MO Theory Molecular Orbital Theory (AKA: MO Theory) Key Terms o Antibonding orbital: A molecular orbital that is higher in energy than its component atomic orbitals. Placement of electrons into this kind of orbitals raises the total amount of energy in a system, making bonding unfavorable. o Atomic orbital: These orbitals that are associated with only one atom, in contrast to molecular orbitals, which spread across a collection of atoms. o Bonding orbital: This is a molecular orbital that has lower energy than its constituent atomic orbitals. Electrons into such orbitals lower the total energy of the system, this makes bonding favorable. o Bond
