  The understanding of atomic adsorption on graphene is of high importance for
many advanced technologies. Here we present a complete database of the atomic
adsorption energies for the elements of the Periodic Table up to the atomic
number 86 (excluding lanthanides) on pristine graphene. The energies have been
calculated using the projector augmented wave (PAW) method with PBE, long-range
dispersion interaction corrected PBE (PBE+D2, PBE+D3) as well as non-local
vdW-DF2 approach. The inclusion of dispersion interactions leads to an
exothermic adsorption for all the investigated elements. Dispersion
interactions are found to be of particular importance for the adsorption of low
atomic weight earth alkaline metals, coinage and s-metals (11th and 12th
groups), high atomic weight p-elements and noble gases. We discuss the observed
adsorption trends along the groups and rows of the Periodic Table as well some
computational aspects of modelling atomic adsorption on graphene.
