<span>Because protons are positively charged and neutrons have no charge then it is safe to say that such an atomic model would have the positive charge concentrated in the center of an atom (option d).</span>
CIO4-=-1
CI=4O=-1
O has a 2- oxidation change so

CI+(-8)=-1
CI=-1+8=7
So the oxidation number of chlorine is 7 in this case
