Which properties are common between alkali metals alkaline earth metals halogens noble gases?

Alkali metals, alkaline earth metals, halogens, and noble gases each belong to distinct groups on the Periodic Table, exhibiting unique properties. However, they share common trends such as being reactive, with alkali and alkaline earth metals being highly reactive, particularly with water, while halogens are reactive nonmetals. Additionally, all these groups have distinct electron configurations that dictate their reactivity and bonding behavior, and they all play essential roles in various chemical reactions and compounds. Noble gases, while generally inert, are characterized by a complete valence shell, which distinguishes them from the more reactive groups.
