ALKALI METALS ---> Melting and boiling points of alkali metals are quite low and decrease down the group due to weakening of metallic bond. Fr is liquid at room temperature
 
ALKALINE EARTH METALS → These metals have higher melting and boiling points tahn those of alkali metals because of greater number of bonding electrons. The melting and boiling point decreases down the group with the EXCEPTION OF MAGNESIUM
