Oxidation number and oxidation state -

A term that is often used interchangeably with the oxidation number is the oxidation state. This implies oxidation number denote the oxidation state of an element.

-

 

 Let's examine each species

MnO_{4}^{-},\ M_{n}:+7

Cr\left ( CN \right )_{6}^{3-},\ Cr:+3 

NiF_{6}^{2-},\ Ni:+4

CrO_{2}Cl_{2}:Cr:+6

\therefore The solution is 4
