Which two groups of elements in the periodic table are the most reactive would it be alkaline earth, metals, and halogens or alkaline metals and halogens or halogens and noble gases or noble gases, and alkali

Answer 1

The two groups of elements in the periodic table that are the most reactive are the alkali metals (Group 1) and the halogens (Group 17).

Alkali metals are highly reactive, especially with water and halogens, while halogens are also very reactive, particularly with alkali metals to form salts. Noble gases (Group 18), on the other hand, are generally non-reactive due to their stable electron configurations.
