The ion has a positive charge and its Radius is smaller than that of the atom

Anika Avery · Answer 2

The answer is # 1.

When the atom has less electrons than the original, it means it is less negative because electrons are the negative particles of an atom. Being less negative means that it has a positive charge.

Having less electrons means there are less electrons to orbit the atom, which means it's radius is decreased; this makes the atom looks smaller.
