Detailed explanation-1: -Metals are lustrous, malleable, ductile, good conductors of heat and electricity. Other properties include: State: Metals are solids at room temperature with the exception of mercury, which is liquid at room temperature (Gallium is liquid on hot days).
Detailed explanation-2: -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).
Detailed explanation-3: -Metals have a unique ability to reflect light from their pure surface (without impurities). This results in a shiny surface and this property is known as lustre.
Detailed explanation-4: -high melting points. good conductors of electricity. good conductors of heat. high density. malleable. ductile.
