Question

Zirconium is a transition element, but Zinc is not. Why?

• A. Both \(Zr^{3+}\) and \(Zn^{2+}\) ions are colourless and form white compounds
• B. In case of transition elements, d-orbitals are partially filled, but in Zn they are completely filled
• C. Last electron is added to 4s level in case of Zn
• D. Both Zr and Zn do not exhibit variable oxidation states

Hint:

Zn, Cd, and Hg are generally not considered transition elements because their atoms and common ions contain completely filled \(d^{10}\) configurations.

Answer 1

The Correct Option is B
