Electron Rules

100

This is the rule that states that most elements (excluding transition metals) will have a completely filled energy level at 8 electrons. 

the Octet Rule

200

This principle states that an electron occupies orbitals in order from lowest energy to highest.

Aufbau Principle

300

This principle states that atomic orbitals can hold only two electrons at most and they must have opposite spins.

Pauli Exclusion Principle

400

This rule states that in a sublevel with more than one orbital, put one electron into each orbital before putting 2e-into any one orbital. (electrons like to be spread out from each other, if possible)

Hund's Rule
