Is this the correct oxidation numbers for H and O in hydrogen peroxide H2O2; H 1+, O 1- . Why or why not ?


Yes ,  H +1, O 1-  is the correct oxidation state of each element H and O in H2O2 because as per oxidation number rules the O oxygen in perooxides should be -1 and H is and +1 so these are correct oxidation numbers .


Yes H is +1 and O is -1 is peroxides so these oxidation numbers are correct .
