Question

the oxidation state of oxyrgen is​

Answer 1

Answer:

The oxidation state of the oxygen is -2, and the sum of the oxidation states is equal to the charge on the ion.

Answer 2

oxygen have 5 oxidation states.

In all the oxides,oxygen has an oxidation state of −2. Eg. CO2,CO

In all peroxides (oxygen-oxygen linkage), oxygen has an oxidation state of −1. For example, consider H2O2, here H is less electronegative so it will acquire a charge of +1 and to balance the 2 positive charge of 2 H-atoms,each oxygen atom will acquire a charge of −1.

In all superoxides (KO2,CsO2,RbO2), oxygen has an oxidation state of −12,this is because K,Cs,Rb, being elements of the first group and less electronegative than oxygen acquire a charge of +1, to balance it, each oxygen atom acquires a charge of −12.

In one of the exceptions OF2, the fluorine being more electronegative acquires a charge of −1 and to balance the −2 charge of 2 fluorine atoms oxygen acquires a charge of +2.

As last, there is O2F2, similarly here to balance the −2 charge on 2 F-atoms each oxygen atom acquire a charge of +1.
