The alkaline earth metals on the periodic table’s Group 2A (or IIA) are beryllium (Be), magnesium (Mg), calcium (Ca), strontium(Sr), barium, and radium (Ra): They are both harder and less reactive than Group 1A” s alkali metal beads. The name derives from the fact that these metal oxides dissolved in water and remained solid at the temperatures that were not accessible to ancient alchemists. In their highest-energy orbitals, the alkaline metals have two valence electrons (ns2).
