Type: MCQ-conceptual-Medium-Class 12
Which of the following statements about the enthalpy of atomisation of transition elements is true?
A
Higher enthalpies are due to stronger interatomic interactions.
B
Enthalpy of atomisation decreases with an increase in unpaired electrons.
C
The enthalpy of atomisation is lowest for elements with fully filled d-orbitals.
D
Transition elements have lower enthalpies of atomisation than actinoids.
Correct Answer
Option A
Detailed Explanation
The NCERT context mentions that transition elements exhibit higher enthalpies of atomisation due to large numbers of unpaired electrons leading to stronger interatomic interactions.
