Abstract
The adsorption of an atom with a single valence s electron (hydrogen, alkali metals) or with a single valence p-vacancy (halogens) on the surface of a graphene monolayer is considered and the adatom charge is calculated. Cases where the adatom-graphene σ bonds are formed with the participation of p, sp, sp 2, and sp 3 states of carbon atoms are analyzed. It is established that the character of hybridization rather weakly influences the charge transfer. The character of adatom charge variation in the series Li → Cs and F → I is analyzed.
