Where are the most active nonmetals located on the periodic table

The most active nonmetals belong to the halogen family, which sits to the left of the noble gases on the right side of the periodic table. The halogens are so reactive that they are never found in nature by themselves. The elements fluorine, chlorine, bromine, iodine and astatine make up the halogen family.

Group 7

Explanation:

Elements in the group 7 of the periodic table are known as the halogens. They are the most active/reactive nonmetals because they have just one electron to receive in order to achieve there octet configuration. They react easily with elements in group 1 (in the same proportion) since group 1 elements have just one electron in there outermost shell. Halogens easily form acids with hydrogen by sharing the only electron hydrogen has with its own valence electron via covalent bonding. They however undergo ionic bonding with the remaining members of group 1. They also react with metals in group 2, 3 and 4 in different proportion.
