Every atom contains all of the properties of its element. Tungsten's atomic mass is 183. The atomic mass is obtained by calculating the average number of neutrons plus the protons in the tungsten isotope. There are five different stable isotopes of tungsten containing 108, 110, 106, 109, and 112 neutrons. The average of these …
Description. Tungsten was recognized as a distinct element in 1779 by Peter Woulfe, but not isolated until 1783, by Jose and Fausto d'Elhuyar. The average tungsten concentration in the earth's crust is ~0.006%. Tungsten occurs naturally as tungstate, mainly in compounds such as wolframites and scheelites.
