Which of the following does not have valence electron in 3 d...

Phosphorus (P) has electronic configuration 1 s², 2 s², 2 p^{6,} 3 s^{2,} 3 p³ Therefore, no valence electron is present in the $3 d$ subshell. Fe (III) has electronic configuration :$$\begin{aligned}& 3 d⁵ 4 s⁰ \\ & \operatorname{Cr}(\mathrm{I}): 3 d⁵ 4 s⁰ \\ & \operatorname{Mn}(\mathrm{II}): 3 d⁵ 4 s⁰ \end{aligned}$$
