Transition metals with lowest melting point is
Detailed Solution for Test: d & f-Block Elements - Question 4

- Mercury (Hg) is the transition metal with the lowest melting point.
- It is the only metal that is liquid at room temperature, with a melting point of -38.83°C.
- The low melting point is due to weak metallic bonding in mercury's lattice structure.
- Mercury's electrons are more tightly bound to the nucleus, reducing the overlap of electron clouds that contribute to metallic bonding.
- This results in weaker forces holding the atoms together, leading to a low melting point.
