Explanation:
Detailed explanation-1: -Thus metals are electropositive elements. They are characterized by bright luster, hardness, ability to resonate sound and are excellent conductors of heat and electricity.
Detailed explanation-2: -Metals are lustrous, malleable, and are good conductors of heat and electricity. Non-metals are elements that do not share the properties of metals.
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). Most of the metals are solids at room temperature, with a characteristic silvery shine (except for mercury, which is a liquid).
