Out of atoms H and He one with smaller radius should be identified. Concept introduction: As one moves from top to bottom the shells expands and size increases, while it decreases as one move along the period because of gradual increases in effective nuclear charge. This in turn increases influence of nucleus on valence electron and shrinks the radius along the horizontal row.

Solution Summary: The author explains that out of atoms, one with smallest radius should be identified. As one moves from top to bottom the shells expand and size increases, while it decreases as one move along the period.
Definition Definition Number of protons in the nucleus of an atom. It uniquely identifies an element, as the number of protons determines the element's properties. The periodic table of elements is arranged based on increasing atomic numbers, allowing scientists to easily locate and study elements.
