The oxidation number of Mn in manganese VII oxide is +7.
MnO2 manganese(IV) oxide. Oxygen has a -2 oxidation state (oxidation state is a better term here as oxidation number is better used for complexes- they give the same answer for this compound)
+8 is the usually quoted maximum oxidation number. Osmium tetra-oxide has this. +7 is fairly common as manganese in KMnO4 has this oxidation number.
Manganese is a metal element. It shows the largest oxidation number.
The oxidation number of an element depend on another element it react with to form a compound e.g manganese(iv)oxide mno4 the oxidation number of oxygen there is four while the oxidation number of manganse is 7 in most radox reaction the oxidation number of oxygen is usually 4 when writing the full equation

The common oxidation number of manganese are +2, +4 and +7.
For some oxidation reactions Lead(IV) oxide can be used in place of Manganese dioxide

Manganese oxidation state = +7 So, it is also called Manganate(VII)
Permanganic compounds contain manganese in a +7 oxidation state. Since oxygen in oxides always has a -2 oxidation state, the formula for permanganic oxide is Mn2O7.
The oxidation number of manganese in KMnO4 is 7+.
+6 for Mn
+2
