Where are the most reactive nonmetals elements found in a periodic table

The correct answer is: They are found in the upper right portion of the periodic table, before the noble gases.

Explanation:

The most reactive nonmetals elements of the periodic table are the halogens (group 17). This group is formed by 5 different elements: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At); from which fluorine is the most reactive out of the 5.

These elements are the most reactive nonmetals because they have one space in their valence electron shells.

the fossil record provides evidence of a common ancestor to many species.
