Vedclass · Answer

(A) Atomic radius of the elements decreases across a period from left to right due to an increase in effective nuclear charge. On moving down a group,the number of shells increases,so the atomic radius increases. Amongst isoelectronic species,the ionic radius increases with an increase in negative charge or a decrease in positive charge. Therefore,the statement that 'smaller the positive charge on the cation,smaller is the ionic radius' is incorrect,because a smaller positive charge means a larger ionic radius.
