Electrons in Atoms
... • Orbitals of an atom will fill so that the atom is in its most stable state. There are 3 rules that govern this: • Aufbau Principle- e- occupy lowestenergy orbitals first • Pauli Exclusion Principle- 2 e- in same orbital must have opposite spin • Hund’s Rule- e- occupy orbitals of the same energy s ...
