Identify the transition element :–
| A. |
`1s^2, 2s^2 2p^6, 3s^2 3p^6, 4s^2` |
| B. |
`1s^2, 2s^2 2p^6, 3s^2 3p^6 3d^(10), 4s^2 4p^1` |
| C. |
`1s^2, 2s^2 2p^6, 3s^2 3p^6 3d^(10), 4s^2 4p^6` |
| D. |
`1s^2, 2s^2 2p^6, 3s^2 3p^6 3d^2, 4s^2` |
 |
Transition elements are those elements which posses poatrly filled d-subhshells in their elementary form or their commonly occuring ions i.e., `(n–1)d^(1–10) ns^(1–2)` .
