tungsten, or wolfram, is a chemical element with the symbol w and atomic number 74. the name "tungsten" comes from the former swedish name for the tungstate mineral "scheelite", "tung sten" or "heavy stone". tungsten is a rare metal found naturally on earth almost exclusively combined with other elements in chemical compounds rather than alone. it was identified as a new element in 1781 and first isolated as a metal in 1783. its important ores include wolframite and scheelite.

oxygen, sulfur, and selenium are nonmetals, and tellurium is a metalloid, meaning that its chemical properties are between those of a metal and those of a nonmetal. it is not certain whether polonium is a metal or a metalloid. some sources refer to polonium as a metalloid, although it has some metallic properties. also, some allotropes of selenium display characteristics of a metalloid, even though selenium is usually considered a nonmetal. even though oxygen is a chalcogen, its chemical properties are different from those of other chalcogens. one reason for this is that the heavier chalcogens have vacant d-orbitals. oxygen's electronegativity is also much higher than those of the other chalcogens. this makes oxygen's electric polarizability several times lower than those of the other chalcogens.
