(a)
Interpretation: The oxidation state of all atoms in
Concept Introduction: Oxidation state indicates the number assigned to an element in a compound, which indicates the number of electrons transfer by the atom of that element.
It can be calculated with the help of standard oxidation states of certain elements like halogens with -1 oxidation state, alkali metals with +1 and alkaline earth metals with +2 oxidation state whereas O shows -2 oxidation state.
