Which of the following does not have valence electron in 3d-subshell?
Show Hint
- Fe(III)
- Mn(II)
- Cr(III)
- P(O)
The Correct Option is D
Solution and Explanation
Step 1: Identify the electron configuration.
The valence electrons of elements are those in the outermost shell, including the 3d subshell. Phosphorus (P) in the \( P(O) \) state has no electrons in the 3d subshell, unlike the other elements.
Thus, the correct answer is (4).
