Detailed explanation-1: -Heat conduction is the property of metals. The valence electron in metals is free to move between the atoms. As a result, metals are excellent electrical conductors. These electrons can also transport energy in the form of heat, making metals heat conductors.
Detailed explanation-2: -In the case of metals, there are a high amount of free electrons, and hence heat conduction primarily leads to electronic conduction. In metals, the free electrons can move freely throughout the solid and thus transfers the thermal energy at a very high rate as compared to insulators.
Detailed explanation-3: -Metals are good conductors of heat and electricity, and are malleable (they can be hammered into sheets) and ductile (they can be drawn into wire).
Detailed explanation-4: -high melting points. good conductors of electricity. good conductors of heat. high density. malleable. ductile.
