Which one of the elements with the following outer orbital configurations may exhibit the largest number of oxidation states?

A $3 d^{5} 4 s^{1}$
B $3 d^{5} 4 s^{2}$
C $3 d^{2} 4 s^{2}$
D $3 d^{3} 4 s^{2}$

Solution & Step-by-step Explanation

The number of oxidation states depends on the number of electrons available in both n s and (n - 1) d orbitals for bonding. 3 d^{5} 4 s^{1} (Chromium): Can show + 2 to + 6 . 3 d^{5} 4 s^{2} (Manganese): Can show + 2, + 3, + 4, + 5, + 6, + 7 . This is the highest in the 3 d series.
