Dear School Tie-up | comes out to b +10....but itz not correct.... in itz real structure....one Cr atom is attached  to 4 oxygen atoms....double-bonded with two O-atoms and single bonded with the rest two O-atoms.... oxygen being more electronegative attracts the shared electron towards itself....the double-bonded O-atoms retains 4 electrons while the single-bonded retains 2 electrons..... in that case...one Cr-atom loses 6 electrons and it retains a positive charge of +6...... Its 6 due to the presence of 2 peroxide bonds,.... you can get the oxidatuion number by the structure of CrO5 and i have attached the image also so please check the.
