because when electron are aded to form a anion , the increase of electron_elctron repulsion cause the elcectron to spread out in more spaces
The negative ionic radius is larger than the neutral atomic radius
in the case of non-metals, the anions are formed by the addition of electrons. So the ionic radius is larger than that of the atomic radius
the positive ionic radius is smaller than the neutral atomic radius
K has a larger atomic radius than Li. This is because atomic radius generally increases down a group in the periodic table, so potassium (K) being below lithium (Li) in Group 1 will have a larger atomic radius.
Barium has a larger atomic radius than tin.
The additional electron(s) go into the next available orbit, so the anion is always slightly larger than the neutral analog.

Bromine has a larger atomic radius than magnesium. Atomic radius generally increases as you move down a group on the periodic table, so bromine, being below magnesium, has a larger atomic radius.
K+ has larger radius
