A nonmetallic element, red in powder form, black in vitreous form, and metallic gray in stable crystalline form, resembling sulfur and found as an impurity in pyrites or obtained as a byproduct of electrolytic copper refining. It is widely used in rectifiers, as a semiconductor, and in xerography. Its photovoltaic and photoconductive actions make it useful in photocells, photographic exposure meters, and solar cells. Atomic number 34; atomic weight 78.96; melting point (gray) 221°C; boiling point (gray) 685°C; specific gravity (gray) 4.79; (vitreous) 4.28; valence 2, 4, or 6.
A region of the southeast United States generally including Alabama, Georgia, South Carolina, and Florida.
A southeastward direction, point, or region.
a toxic nonmetallic element related to sulfur and tellurium; occurs in several allotropic forms; a stable grey metallike allotrope conducts electricity better in the light than in the dark and is used in photocells; occurs in sulfide ores (as pyrite)
