Question

campare the atomic radius of calcium atom and calcium ion which one has large radius ?

Answer 1

Answer:

the neutral Ca atom has a larger radius than the Ca2+ ion. This is because the loss of electrons reduces the shielding effect between the electrons and the nucleus, so the attraction of the nucleus for the electrons is greater, reducing the radius. For b) S2− has a larger radius than the neutral S atom.
