The symbol of chromium is Cr. It has variable charges +2,+3. Its symbol along with its charges is Cr2+ or Cr3+.
there is no element with the symbol R, so perhaps it is meant to read CrCl6 which is Chromium Chloride. Hope this helps! for more info on Chromium Chloride visit http://en.wikipedia.org/wiki/Chromium(III)_chloride
