WebTrends in Group 2 Compounds. Group 2 Elements are called Alkali Earth Metals. They are called s-block elements because their highest energy electrons appear in the s subshell. Progressing down group 2, the atomic radius increases due to the extra shell of electrons for each element. Going down the group, the first ionisation energy decreases.
