What's a substance called that is shiny, malleable, and poor conductor of electricity? a.) metal b.) non-metal c.) metalloid note: this question is confusing me, because metals are shiny, malleable, yet good conductors of electricity according to google. then non-metal's are poor conductors of electricity, yet brittle and not often shiny. metalloid is probably the answer, however it does still say their relatively good conductors. xd.
