1. Molecular Orbital Theory
Atomic orbitals mix together and make:
Bonding Orbitals
Electrons in these orbitals help hold atoms near each other
Antibonding Orbitals
Electrons in these orbitals push atoms apart from each other
Nonbonding Orbitals
Electrons in these orbitals have no effect on bonding
Molecular Orbitals can:
be Sigma or Pi
be spread over multiple atoms
