S Elements

S Elements . Groups 1 and 2. Properties of Group 1A. These are (except for hydrogen) soft, shiny, low-melting, highly reactive metals, which tarnish when exposed to air. The valence electron is easily lost, forming an ion with a 1+ charge. larger atomic radii and low ionization energies
