Electrons In Atoms

Electron Configuration

1) Find the number of electrons in the atom

2)Find the principal energy level of the atom also know as N

3) Determine the amount of sub-levels

4)Use Hunds's, Aufbaus's, and Pauli's rules to get the sublevels of the electrons

Orbital Configuration

Lowest Energy Level - Highest Energy Level

When electrons are added the energy of the orbital is changed

Having a full orbital is the best possible situation, the next best would be having a half orbital with a lower energy level
