We know that the metallic characters increase down a group whereas it decreases across a period . In this sense what about the non-metallic characters of the non-metals?

Solution

Ans- Non- metallic character increases with the increase in electronegativity of non-metals.Across a period, the tendency to gain an electron increases, so non- metallic character increases.Whereas, down the group, the tendency to gain an electron decreases, therefore the non- metallic character decreases.
