Group I elements are the alkali metals

Group II elements are the alkali earth metals

• The most reactive metallic group of metals are the alkali metals.
• They are followed by metals in the second group which are the alkali earth metals.

Therefore, elements in groups I and II are the most reactive metallic groups.

Group I elements prefers to lose one electron to attain an octet configuration.
