A reduction of atomic size as the increase in atomic number

Answer 1

with increase in atomic number in moving down a group the number of the principal shall increase and therefore in the size of the atomic increase but in case of F block element there is a steady decrease in atomic size with increase in atomic number due to lanthanide contraction
