So a positive oxidation state. Now, these guys are highly reactive when you mix them with nonmetals and they form ionic compounds. For example, if we react these guys with an H, they will form something called metal Hydrides nah, lih, et cetera, in which the NA and the li both have a positive one oxidation state. 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.
