Operationally, metals are good conductors of electricity, and their resistance increases with temperature because it is caused by vibrational scattering of conduction electrons. This distinguishes them from even the best electrically conducting semiconductors, because in semiconductors resistance decreases with temperature as more electrons are thermally excited to the conduction band.

Metals are conductive, lustrous, malleable, ductile, 3 are magnetic, and they produce Hydrogen gas when placed in an acid. Non-metals do none of this. You have to be careful around metalloids though, they can go both ways on different things.

Metals will “give light” when we put them in an electric circuit, non-metals will not.
