The atom having larger atomic radius has to be selected among N a and C s Concept Introduction: Atomic radius is the distance between the atomic nucleus and outermost shell having electrons of an atom. From the atomic radius, the size of atoms can be visualized Down the group, the principal quantum number increases and thus the size of orbital also increases which results in the increase in atomic radii.
