Orbital Filling
There are a series of rules that are followed when placing electrons into orbitals to give the ground state (most stable) electron configuration of an atom.

Classification of Electrons
Electrons within an atom can be classified into three categories:
- Inner (core) electrons
- Outer electrons
- Valence electrons
It will soon be important to identify types of electrons, especially those that are valence, because those are used in bonding.
