Watch two groups of elements in the periodic table are the most reactive one point

Answer 1

The two groups of elements in the periodic table that are the most reactive are the alkali metals in Group 1 (such as lithium, sodium, and potassium) and the halogens in Group 17 (such as fluorine, chlorine, and iodine). These elements are highly reactive because they have a tendency to gain or lose electrons in order to achieve a stable electron configuration. Alkali metals readily lose their single valence electron to form positive ions, while halogens readily gain one electron to form negative ions.
