Ionization Energy Notes:

Ionization energy is the minimum amount of energy required to remove the most loosely bound electron, the valence electron, of an isolated neutral gaseous atom or molecule. It is expressed as X + energy → X+ + e- where X is any atom or molecule capable of ionization, X+ is that atom or molecule with an electron removed, and e- is the removed electron. This is an endothermic process. In chemistry, the unit is the amount of energy required for all of the atoms in a mole of substance to lose one electron each: molar ionization energy expressed as kilojoules per mole (kJ/mol) or kilocalories per mole (kcal/mol).
