Number of electrons are rarely (if ever) used. In principle sum of the coefficients of gaussians should be equal to the number of electrons. Ions from nonions are distinguished by just addition charge on the element column. Example: ATOM 4175 CLCL I 1 5.299 23.521 60.812

[ccp4bb] Li ion scattering factor

Dear All, We have a structure under refinement with a putative Li bound to a potentially important allosteric site. I'd assumed that Li+ would lose an electron and have weaker scattering than Li Metal, but the entry for atomsf.lib has the same # of electrons for both entries while the entries
