Question

hey guys!!!!
does atomic size increase or decrease while moving down the group nd why?

Answer 1

This is caused by the increase in the number of protons and electrons across a period. One proton has a greater effect than one electron; thus, electrons are pulled towards the nucleus, resulting in a smallerradius.Atomic radius increases from top to bottom within a group. This is caused by electron shielding.

mark as brainliest please

Answer 2

Hyy✌✌

Generally, Atomic size increases on moving down the group

Because the number of shells increases down the group while shielding effect increases
