Question

How and why does the nonmetallic character vary as we go a) From left to right along a period b ) Down a group

Answer 1

Metallic character decreases across a period and increases down the group.
I f you look at the periodic table, all the non metals are on the right hand side of the table.
Nuclear charge increases across a period.
Therefore it easier to gain electrons.
