Chemistry - Complete d-block Question with Solution | TestHub

The options provided are incorrect and do not relate to the question about the enthalpy of atomization of Zn. The question asks for the reason why Zn has the lowest enthalpy of atomization in the Sc to Zn series.

Correct Answer:

Zn has a completely filled d-orbital ($3d^{10}$) and does not form strong metallic bonds due to the absence of unpaired electrons, leading to weak interatomic forces and thus a low enthalpy of atomization.
