-Increase from right to left because the attraction between valence electrons and the nucleus is weaker
-Increase as you move down because the atomic size is bigger
-A bigger atomic size has to do with the outer shells being farther away
-When the electrons on the valence shell have a little attraction to the nucleus it can loose electrons easily
-Nonmetallic characters deal with the ability to gain electrons

Metallic Character

-How easily an atom can loose electron
