Metals right beside the alkali metals or group 2. Slightly less reactive than alkali metals, but the second most reactive elements in the periodic table. Cations in their ionic for
Relationship between two species in which one kills and consumes the other
Relationship in which one species benefits while the other is left unaffected
Mass/ Volume, how compact something is
