Choose an option

Show full solutionCorrect option: B
Correct answer
BAg

Step-by-step explanation

Transition metals have high melting point due to their high enthalpy of atomisation. They form strong metallic bonds with unpaired electrons.

Melting point of Ag=961.8°C

Melting point of Cs=28.5°C

Melting point of Ga=30°C

Melting point of Hg=-38.83°C

Cs,Ga and Hg are liquid at or near room temperature.

Among the given options Ag has the maximum Melting point, as it belongs to transition metal series.
