Using the periodic table, choose the more reactive non-metal. s or as

More reactive non-metal is Sulfur (S).

Explanation:

Non-metals are defined as the elements which have the tendency to gain electrons.

A reactive non-metal is the one which gains electrons easily.

In a periodic table, the reactivity of non-metals increases as we move across a period and decreases as we move down the group.

Sulfur belongs to group 16 and period 3 of the periodic table while Arsenic belongs to group 15 and period 4 of the periodic table.

Hence, Sulfur is a more reactive non-metal.
