High Victor, my response to Abderrahmane Reggad appears perhaps a little harsh. It was not meant that way. I wanted to emphasize that in my view the idea of telling Wien2k (or any other DFT program) its result (where the electrons are) and to simulate properties from there is completely

DFT in general and Wien2k especially are there to tell you with remarkably high precision what the charge distribution in a given structure actually looks like. Thats FAR better than any hand-waving Ni is 2+, O 2-. If you don't like what DFT tells you and want to draw some fictitious ionic

Dear wien users I want to simulate the NiO compound in its ionic state. We know that the Ni and O atoms have in their neutral state the atomic numbers 28 and 8 respectively. Now, if we want to study the ionic state of the compound Ni+2O-2, should we modify the atomic numbers to Z=26 for Ni and
