1.	Justify the following statements: a) Cations are smaller in size than the corresponding atom. b) Size of the atom increases as we move down a group. c) Atomic size decreases as we move across a period.
Answer» Solution :a) Cations WOULD have lost outermost-shell electrons and HENCE their size is smaller than the corresponding atom. B] Addition of new shells, going down a group, increases the distance between the outermost electrons and the nucleus. c] Increase in nuclear CHARGE, tending to pull electrons closer to the nucleus, reduces the ATOMIC size of elements, along a period.
