उत्तर
(ii) and (iii)
Explanation -
The atomic radius(r) of an atom is the distance between the centre of the nucleus and the outermost shell of an isolated atom. In representation (ii), the outermost shell is K and atomic radius is correctly depicted from centre of nucleus to shell K while in representation (iii), the outermost shell is M and atomic radius is correctly depicted from centre of nucleus to shell M.
