Is silicon considered to be metal or non-metal? - Quora

In this context silicon is a nonmetal. It is also commonly recognised as a metalloid (i.e. a weak nonmetal) since it is a semiconductor and has an intermediate ionisation energy, and an intermediate electronegativity value. When it melts, silicon becomes a reasonable metal with an electrical conductivity similar to that of liquid mercury.
