उत्तर

The size of an atom is indicated by its radius.

Explanation:

The size of an atom is defined by its atomic radius, which is the distance from the center of the nucleus to the outermost shell of electrons. While the number of shells influences the size, the physical dimension itself is specifically measured and referred to as the radius.
