Question

The trasition metals exhibit higher enthalpies of atomisation due to:

• A. their ability to show variable oxidation states
• B. the presence of incompletely filled $d-$subshell
• C. their ability to exist in the solid state with unpaired electrons
• D. strong interatomic interaction which arises because of having large number of unpaired electrons in their atoms

Answer 1

The correct option is D strong interatomic interaction which arises because of having large number of unpaired electrons in their atoms

Transition metals contain large number of unpaired electrons.
Due to this strong interatomic interaction is present.
This results in higher enthalpies of atomization.
