Question

How will the tendency to gain electron change as we go from left to right across a periods why

Answer 1

The tendency to gain electron charge will decrease, i.e., the electropositivity will decrease, thus developing non metallic characteristics. As the atomic radius decreases the nuclear charge increases thus a non-meatllic characteristic is formed!

Answer 2

Answer:

Explanation:

Tendency to gain electrons increases from left

to right in a period because atomic size goes on

decreasing and effective nuclear charge increases.
