Question:
Which from following elements is NOT regarded as transition element?
Which from following elements is NOT regarded as transition element?
Show Hint
Completely filled d-orbitals (\(d^{10}\)) $\Rightarrow$ not a transition element.
Updated On: Apr 26, 2026
- \(\text{Ni}\)
- \(\text{Fe}\)
- \(\text{Ag}\)
- \(\text{Hg}\)

Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Concept:
A transition element must have:
Step 2: Conclusion. Since Hg has completely filled d-orbitals in both atom and common ions: \[ \text{Hg is not a transition element} \]
A transition element must have:
- Partially filled d-orbitals in atom or
- At least one oxidation state with incomplete d-orbitals
- Ni, Fe â partially filled d-orbitals
- Ag â forms ions with incomplete d-orbitals
- Hg â electronic configuration: \(d^{10}\) (completely filled)
Step 2: Conclusion. Since Hg has completely filled d-orbitals in both atom and common ions: \[ \text{Hg is not a transition element} \]
