graphene unit cell representation shows very small atoms
when the graphene material system is displayed as a unit cell the carbon atoms are really small. In the diamond lattice or the bucky ball that is not the case. Can this get so the atoms are more visible?

+2 -1 Login to vote The reason for small carbon atom size is that the default atomic size for carbon is quite small in pymol. The atomic radius of atom depends on the atomic number and higher the atomic number larger the atom radius. That is the reason silicon appears fine. Another reason why in graphene atoms look smaller is the larger bond lengths compared to diamond and buckyball(both carbon cystals.) Two solutions possible: easy one : select some other heavier atom in place of carbon (can be done in the code).

difficult one: change the default setting for carbon in pymol( can be done by pymol admin.)
I hope this answers the question.
