The Group 2A(2) elements are called alkaline earth metals because their oxides give (alkaline) solutions and melt at such temperatures that they remained as solids ("earths") in the alchemists fires. denser low for 2A metals than larger lower The melting and boiling points are much for the corresponding 1A metals. ences smaller oxidizing Compared to corresponding Group 1A(1) elements, Group 2A(2) elements have metallic bonding and atomic sizes which makes them harder and than the alkali metals. weaker basic twice acidic Group 2A(2) elements have atomic radii and ionization energies than Group 1A(1) elements. high higher reducing half Like alkali metals, the alkaline earth metals are strong agents. less stronger Group 2A(2) salts have much lattice energies than Group 1A(1) salts because the 2A cations are _and have the charge, resulting in much _ charge densities and solubilities for 2A salts.
