When we move across the period i.e. from left to right, the atomic size decreases due to increase in atomic number(Nuclear pull increases).But when we move from top to down in a group, in this case also there is an increase in the atomic number i.e. increase in nuclear pull then why the size increases?If the logic is the increase in number of shells then in the both cases it can be applied.
