Even though nonmetals form anions, which are larger than the original atoms, ionic radius decreases from left to right across a period for nonmetals and metals. The reason for this is because atomic radius also decreases from left to right across a period, and this makes any increase in ionic radius negligible.
What causes ionic radius to increase slightly when going from metals to nonmetals?
