The highest oxidation state is exhibited by the transition metals with configuration:

Options

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

Answer

C

Explanation

Maximum oxidation state of transition elements=number of electrons present in ns-orbital+number of unpaired electrons in (n-1)d-orbitals.
