Question

Which of the following is not a property of a transition metal?

• A. They are lustrous
• B. They are malleable
• C. They are ductile
• D. They have low boiling points

Answer 1

The correct option is D They have low boiling points

The transition metals exhibit all the characteristics of metals. They are hard, lustrous, malleable, less volatile and ductile. They have high melting and boiling points, high thermal and electrical conductivity and high tensile strength.
Transition elements form very ​strong metallic bonds.​ This arises due to unpaired electrons in the (n−1)d subshell.​ Greater the number of valence electrons​; stronger is the ​resultant bonding and higher will be the ​boiling point.​
