NEET Chemistry Transition Elements MCQ Question
Type: MCQ-fact-Medium-Class 12
Why do transition elements exhibit higher enthalpies of atomisation compared to other elements?
A
They have a large number of unpaired electrons.
B
They have completely filled d orbitals.
C
They possess weak interatomic interactions.
D
They have lower atomic masses.
Correct Answer
Option A
Detailed Explanation
Transition elements have a large number of unpaired electrons, which leads to stronger interatomic interactions and thus stronger bonding between atoms, resulting in higher enthalpies of atomisation.
