In group I of the periodic table, three elements X,Y and Z have ionic radii 1.33 A˚, 0.95 A˚ and 0.60 A˚ respectively. Giving a reason, arrange them in the order of increasing atomic number in the group.

As we move down a group, the numbers of shells increases and hence the atomic size increases.
Therefore, Z will have the smallest atomic number followed by Y, while X will have the largest atomic number.
So the elements in order of increasing atomic number will be Z
