The order of the increasing atomic size of
Concept introduction:
Atomic size is the distance from the nucleus to the valence shell where the valence electrons are situated. It is very difficult to measure due to absence of any definite boundary.
Along the period, the atomic size decreases due to the increse in the effective nuclear charge.
Down the group, the atomic size increases because of addition of new shells in the successive members of the group.
