Question 203,
The answer is, Sr++ is smaller than S--, why? I understand that cations are smaller than anions but Sr is two periods below S, shouldn't it automatically be bigger than S? Also Sr++ is probably around Kr, whereas S-- has a size close to Ar. Kr is one whole period below Ar, should it not be larger than Ar?
