Now, if you mix the metals with water, they will react exothermically to produce a metal hydroxide and H two gas. Let's put this guy's in parentheses gas. So, for example, if you make two moles of sodium in a solid state with two moles of water, you will get two moles of metal hydroxide and 1 mol of H two or diatomic gas. Now, let's look at the second type of group right next to our alkaline metals, known as alkaline earth metals. Now, these guys are obviously in group two or group two A on our periodic table. And these guys, just like the alkaline metals, are also part of the metal division.
