Now, since they're metals, they're also malleable duct till and they conduct electricity well. Now, these guys, unlike these guys, form plus two oxidation state. In other words, these guys lose not one electron but two electrons when they react with our nonmetals. So that means they're more likely to lose electrons. Now, our alkaline earth metals are less reactive than the alkali metals, but still react with the nonmetals to form ionic compounds. For example, calcium reacts with hydrogen to form calcium Hydride CAH two.
