There is not just a single characteristic property. Metals, in general—though various exceptions exist—are: good conductors of heat and electricity; malleable and ductile; highly reflective; strong; dense; and donors of electrons in chemical reactions.

These include: color, streak, hardness, luster, diaphaneity, specific gravity, cleavage, fracture, magnetism, solubility, and many more. These physical properties are useful for identifying minerals.
