Question

if the difference in atomic size of : Na- Li = x, Rb- K = y, Fr- Cs = z.Then the correct order will be​

Answer 1

Explanation:

consider about the radius of atoms given above.

Down the grp atomic radius increases because of the shielding effect .

therefore the increasing order of elements above is Li<Na<K<Rb<Cs<Fr .

so if we consider the differences

x>Y>z

explanation is correct but not sure about the ans
