In this manuscript, we introduce the concept of an atomic subset of the \hk\ and study its properties. Also, we give a characterization of the atomic \hk\ and show that there are exactly (up to isomorphism) $n$ atomic \hks\ $H$ with $|H|=n$ for any natural number $n$.
Keywords: \hk, atomic subset and atomic \hk
