And that means because moving charge creates electricity, these guys create or conduct electricity very well. Now, they also form ions with a positive oxidation state. In other words, they're capable of losing electrons very easily, and therefore, they usually form plus one oxidation states. 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.
