What trend does the reactivity of nonmetals show in a periodic table? random changes without any trends on the periodic table
changes according to trends on the periodic table
increases from left to right across the periodic table
decreases from left to right across the periodic table

C) increases from left to right across the periodic table

Explanation: As you move from left to right in the period, we see that the reactivity increases. On the other hand, as you move down a group in the nonmetals, the reactivity decreases. The farther right and up you go on the periodic table, the higher theelectronegativity, resulting in a more vigorous exchange of electrons.

the millers tale is the answer.
