The properties of a metal are as follows.
- Metals are malleable that is they can be drawn into thin sheets.
- They have luster.
- They are good conductor of electricity.
- They are ductile that is metals can be drawn into wires.
Thus, we can conclude that a substance that conducts electricity, is malleable, ductile, and has luster would be classified as a metal.
