Question
Of the following outer electronic configurations of atoms, the highest oxidation state is achieved by which one of them?
A.
$$\left( {n - 1} \right){d^3}\,n{s^2}$$
B.
$$\left( {n - 1} \right){d^5}\,n{s^1}$$
C.
$$\left( {n - 1} \right){d^8}\,n{s^2}$$
D.
$$\left( {n - 1} \right){d^5}\,n{s^2}$$
Answer :
$$\left( {n - 1} \right){d^5}\,n{s^2}$$
Solution :
$$\left( {n - 1} \right){d^5}\,n{s^2}$$ attains the maximum $$O.S.\,{\text{of}}\, + 7$$
