What happens when 1. Sodium reacts with Chlorine 2. Magnesium with Chlorine

1. Potassium is a G1 Element meaning its going to lose 1 electron [+1 Charge] Chlorine is a G7 Element meaning it wants 1 Electron [-1] Charges are balanced out meaning they can make NaCl [Sodium Chloride] 2. Magnesium is a G2 Element meaning its going to lose 2 Electron [+2] Chlorine is a G7 Element meaning it wants 1 Electron. The charges here are Not Balanced, but we make it by adding another Chlorine, making it want 2 Electron [-2] So now we can have Magnesium Chloride [MgCl2] [small 2]
