Which among the following elements has completely filled \(4 \mathrm{~d}\) orbital?
- A Ag
- B \(\mathrm{Cd}\)
- C \(\mathrm{Sc}\)
- D \(\mathrm{Zr}\)
Answer & Solution
Correct Answer
(B) \(\mathrm{Cd}\)
Step-by-step Solution
Detailed explanation
\(
\mathrm{Cd}(\mathrm{z}=48) \Rightarrow[\mathrm{Kr}] 4 \mathrm{~d}^{10} 5 \mathrm{~s}^2
\)
Cd has completely filled \(4 \mathrm{~d}\) - orbital.
\mathrm{Cd}(\mathrm{z}=48) \Rightarrow[\mathrm{Kr}] 4 \mathrm{~d}^{10} 5 \mathrm{~s}^2
\)
Cd has completely filled \(4 \mathrm{~d}\) - orbital.
