Properties of metals, metalloids and nonmetals one or two properties very different from the expected norm, or that are otherwise notable. Sodium, potassium, rubidium, caesium, barium, platinum, gold Manganese Iron, cobalt, nickel, gadolinium, terbium, dysprosium, holmium, erbium, thulium Iridium Gold Mercury Lead Bismuth Uranium Plutonium Boron Boron, antimony Silicon Arsenic Antimony Hydrogen Helium Carbon Phosphorus Iodine Properties of metals, metalloids and nonmetals Metals appear lustrous (beneath any patina); form mixtures (alloys) when combined with other metals; tend to lose or share electrons when they react with other substances; and each forms at least one predominantly basic oxide. Most metals are silvery looking, high density, relatively soft
Antimony telluride It can be transformed into both "n"-type and "p"-type semiconductors by doping with an appropriate dopant. SbTe forms the pseudobinary intermetallic system germanium-antimony-tellurium with germanium telluride, GeTe. Like bismuth telluride, BiTe, antimony telluride has a large thermoelectric effect and is therefore used in solid state refrigerators. Antimony telluride Antimony telluride is an inorganic compound with the chemical formula SbTe. It is a grey crystalline solid with layered structure. Layers consist of two atomic sheets of antimony and three atomic sheets of tellurium and are held together by weak van der Waals forces. SbTe is a narrow-gap semiconductor with a band
