metals
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...
