This lecture introduces the foundational principles of molecular orbital theory, applying the model to explain the existence and stability of diatomic molecules such as H at_2 and He at_2. It elucidates how the combination of atomic orbitals leads to bonding and antibonding molecular orbitals.

Why do some atoms readily form bonds with each other and other atoms don’t? Using molecular orbital theory, we can rationalize why molecular hydrogen is an abundant molecule whereas molecular helium is not. If you want to power your starship with dilithium crystals, you should watch this lecture.
