Rules of Electron Rules of Electron ConfigurationConfiguration1. Afbau principle

◦ An electron occupies the lowest energy orbital that can receive it.

2. Pauli exclusion principle◦ No two electrons in the same atom can

have the same four quantum numbers.3. Hund’s rule

◦ Orbitals of equal energy are each occupied by one electron before any orbital is occupied by a second electron and all electrons in singly occupied orbitals must have the same spin state.

StepsSteps1. determine the number of

electrons to be “addressed”.2. Look at the template or periodic

table and “count”3. You must fill “up” arrows in the

orbitals before filling “down” arrows. 4. The order of filling is 1s, 2s, 2p,

3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d, 7p (these are lowest energy to highest)

◦When these atoms lose or gain electrons, they would have the same number of electrons.

Outer shell configuration◦Valence electrons orbitals and

placementDiamagnetic

◦When all of the electrons in orbitals are paired (up spin and down spin). If one is unpaired it is called paramagnetic)
