Abstract: The adsorption of atomic hydrogen on graphene monolayer is considered using the model density of states (M model). Analytical expressions for the density of states of H adatom and its occupation number $n_a$ are obtained. The main (local) contribution $n_l$ to the total occupation number $n_a$ is due to a local level of the adatom, which occurs below the edge of the continuous spectrum. A variant of the surface molecule approximation in the case of $n_l\gg (n_a-n_l)$ is proposed.
