Three Rules for Filling Electrons into Subenergy Levels/orbitals to make Electron Configuration

1. Aufbau Principle:


2. Pauli Exclusion Principle: (actually not what he said)

a.

b.

3. Hund's Rule:


Let us try one:

Li (3e-):


O (8e-):



From now on, you will expand last subenergy levels into orbitals.

Example 3:


Example 4:
