• Summing up Electron Configuration• What is it : – Likely hood of where electrons can be found around the atom

• What is Important about it: – Energy Levels increase as atoms get bigger– Energy is important for how atoms bond together– 7 Energy levels in the periodic table (In order of Periods)

HOW MANY ORBITALS PER LEVEL
