Question

Why does non metallic character increases from left to right?

Answer 1

Non- metallic character increases from left to right in a period because effective nuclear charge increases from left to right in a period. Due to this effective nuclear charge, the electronegativity increases and the tendency of gaining electrons also increases.

Hope it helps!

Answer 2

metals has ability to loose their electron whereas as non metals are not.

when we move fron left to right nuclear force of attraction increases due to which e- are tightly bounded with nucleas and inc. the non metallic charaters.
