Which of the following ions should have the smallest ionic radius?
A) Sc 3+
B) Ca 2+
C) K+
D) Ar +
E) Cl -
more positive charge will gets lowest ionic size so sc3+ gets smallest than ar+
so first smallest is sc3+(18 electrons ) and then next is Ar+ (17 electrons)

8) Arrange these ions according to ionic radius. Largest to smallest. (K+, Ca^2+, S^2-, CI-, P^3-) 10) Highest to lowest ionization energy. (K, Na, Rb, Li)
Electron radii problem. I thought that P(-3) would have the
smallest radius because it is the same as MG, but the answer key
says CA 2+ is the smallest. Can anyone explain this?
thanks.
