Of the following outer shell electronic configurations of atoms, the highest oxidation state is achieved by which one of them?

Options

A. `(n-1) d^8ns^2`
B. `(n-1) d^5 ns^2`
C. `(n-1) d^3 ns^2`
D. `(n-1) d^5 ns^1`

Answer

B

Explanation

The highest oxidation state is achieved by `(n-1)d^5ns^2` This is because it can lose upto 7 electrons
