Tungsten (also called wolfram) [14] [15] is a chemical element; it has symbol W and atomic number 74. It is a rare metal found naturally on Earth almost exclusively as compounds with other elements.
Naturally occurring tungsten (74 W) consists of five isotopes.Four are considered stable (182 W, 183 W, 184 W, and 186 W) and one is slightly radioactive, 180 W, with an extremely long half-life of 1.8 ± 0.2 exayears (10 18 years).

For stable elements, the formal standard atomic weight (s.a.w.) is added, as published by CIAAW. When the s.a.w. is in interval-notation, its conventional value is added too. Data is retrieved from central s.a.w. values lists, formatting is by {{Infobox element/standard atomic weight format}} (same as {{infobox element}}). Example:
Tungsten, also known as wolfram, is a chemical element with the chemical symbol W and atomic number 74. The word tungsten comes from the Swedish language tung sten directly translatable to heavy stone, [17] though the name is volfram in Swedish to distinguish it from Scheelite, in Swedish alternatively named tungsten.
