The transition elements have a general electronic configuration:

Options

A. `ns^(2) np^(6) nd^(1 - 10)`
B. `(n - 1) d^(1 - 10) ns^(0 -2) np^(0 -6)`
C. `(n - 1) d^(1 - 10) ns^(1 -2)`
D. None of these

Answer

C

Explanation

General electronic configuration of transition of element is [Noble gas] `(n - 1) d^(1 - 10) ns^(1 - 2)`.
