The sum of oxidation number of all the atoms present in any anion = charge on the anion
A) chlorine in ClO4-
Since O will be having -2 oxidation number as it has 6 valence electron and needs 2 electron to complete octet ( O can not expand its octet due to non availability of vacant d orbitals )
Assuming the oxidation number of Cl is y
Hence y + (-2) X 4 = Oxidation number of Cl + oxidation number of O X 4 = charge on ion = -1
Hence y -8 = -1
=> y = oxidation number of Cl = +7
B) manganese in MnO4-
Since O will be having -2 oxidation number as it has 6 valence electron and needs 2 electron to complete octet ( O can not expand its octet due to non availability of vacant d orbitals )
Assuming the oxidation number of Mn is y
Hence y + (-2) X 4 = Oxidation number of Mn + oxidation number of O X 4 = charge on ion = -1
Hence y -8 = -1
=> y = oxidation number of Mn = +7
C) cobalt in Co
Assuming the oxidation number of Mn is y
Hence y = Oxidation number of Mn = charge on ion = 0
Hence y = 0
=> y = oxidation number of Co = 0
