• They are beryllium, magnesium, calcium, strontium, barium, and radium.
• The elements have very similar properties: they are all shiny, silvery-white, somewhat reactive metals, and they are less reactive than the alkali metals at standard temperature and pressure.
• Together with helium, these elements have in common an outer s orbital which is full, that is, this orbital contains its full complement of two electrons, which the alkaline earth metals readily lose to form cations with charge +2, and an oxidation state of +2.
