Carbon is a non-metal, and non-metals are poor conductors of electricity because the bond structure is a "close-packed arrangement." Silicon and germanium which are also in Group IVA are semi-conductors and are classified as metalloids. Metalloids show properties of both metals and non-metals. The have low electrical conductivity compared to metals but conduct more than non-metals. This property makes them useful in small scale electronics.
