Question

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

• A. $(n-1)d^{8}n{s}^2$
• B. $(n-1)d^{5}n{s}^2$
• C. $(n-1)d^{3}n{s}^2$
• D. $(n-1)d^{5}n{s}^1$

Answer 1

The correct option is B $(n-1)d^{5}n{s}^2$

$(n-1)d^{5}n{s}^2\to \left[Mn\right]$
Mn show highest Oxidation state $=+7$.
