Question:medium
Assertion (A): Transition metals have high enthalpy of atomization.
Reason (R): This is because transition metals have low melting points.
Assertion (A): Transition metals have high enthalpy of atomization.
Reason (R): This is because transition metals have low melting points.
Show Hint
High enthalpy of atomization in transition metals results from strong metallic bonding, which also contributes to high melting and boiling points.

- Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of the Assertion (A).
- Both Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of the Assertion (A).
- Assertion (A) is true, but Reason (R) is false
- Assertion (A) is false, but Reason (R) is true.
Show Solution
The Correct Option is C
Solution and Explanation
The high enthalpy of atomization observed in transition metals is attributable to robust metallic bonding and significant d-orbital interactions. Conversely, the general observation of high melting points in transition metals contradicts the notion that low melting points are a characteristic.
