NEET Chemistry Transition Elements MCQ Question
Type: MCQ-fact-Hard-Class 12
What is a primary reason for the higher enthalpy of atomisation observed in transition elements?
A
They have a large number of unpaired electrons.
B
They possess a single oxidation state.
C
They have low boiling points.
D
They exhibit no metallic bonding.
Correct Answer
Option A
Detailed Explanation
The higher enthalpy of atomisation in transition elements is attributed to the presence of a large number of unpaired electrons, which leads to stronger interatomic interactions and thus stronger bonding between atoms.
