What is the comparison between alkali metals halogens and nobel in the periodic table?

Alkali metals, halogens, and noble gases are distinct groups in the Periodic Table, each with unique properties. Alkali metals (Group 1) are highly reactive, especially with water, and have one valence electron. Halogens (Group 17) are also reactive, with seven valence electrons, and readily form salts with alkali metals. In contrast, noble gases (Group 18) are largely inert due to having full valence electron shells, making them stable and unreactive under normal conditions.
