Periodic Table - Important Groups

Group 1; unstable, highly reactive, likely to bond with other elements; extremely soft metals, abundant in nature; low densities, low melting and boiling points, 1 valence electron
Alkali Metals
Group 2; very reactive, likely to bond with other elements, 2 valence electrons
