Question

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

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

Answer 1

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

$(n-1)d^{5}n{s}^2$ can achieve the maximum oxidation state of +7.
