Question

Which of the following statements is incorrect?

(a) Manganese has an abnormally low boiling point

(b) Transition elements have low enthalpies of atomisation

(c) Transition elements exhibit metallic bonding

(d) Transition metals generally have a high boiling point

This question was addressed to me in homework.

My question is taken from General Properties of the Transition Elements (D-Block) topic in portion D and F-Block Elements of Chemistry – Class 12

Answer 1

The correct answer is (b) Transition elements have low enthalpies of atomisation

Explanation: Transition metals generally have high melting and boiling points. Magnesium and technetium have abnormally low boiling points. This is due to the strong metallic bonds between the atoms. They have high enthalpies of atomization.
