What is the Aufbau principle?

• electrons always spin right

• electrons always pair up

• electrons always enter the HIGHER energy orbitals first

• electrons always enter the LOWER energy orbitals first

What is Hund's Rule?

• electrons always pair up first

• electrons must equally distribute between orbitals before pairing up

• electrons always spin right

• electrons must go to the nucleus for instructions
