Isotopes of tungsten

{{Short description|none}} {{Infobox tungsten isotopes}} Naturally occurring tungsten (₇₄W) consists of five isotopes. Four are considered stable (¹⁸²W, ¹⁸³W, ¹⁸⁴W, and ¹⁸⁶W) and one is slightly radioactive, ¹⁸⁰W, with an extremely long half-life of {{val|1.59|0.05|e=18|u=years}}.<ref name="W-180" /> This results in about two alpha decays of ¹⁸⁰W per gram of natural tungsten per year, so for most practical purposes, ¹⁸⁰W can be considered stable. The other naturally occurring isotopes are also capable of alpha decay and so only observationally stable.

Artificial radioisotopes of tungsten have been observed from ¹⁵⁶W to ¹⁹⁷W, the most stable of which are ¹⁸¹W with a half-life of 120.96 days, ¹⁸⁵W with a half-life of 75.1 days, ¹⁸⁸W with a half-life of 69.77 days and ¹⁷⁸W with a half-life of 21.6 days. All of the remaining radioactive isotopes have half-lives less than one day, and most of these less than 8 minutes. The most stable known meta state is ^179m1W with half-life 6.40 minutes. == List of isotopes == {{Anchor|Tungsten-167m|Tungsten-174m3|Tungsten-174m4}} <!--Please delete anchor(s) from the list above or table below if adding a dedicated isotope section(s).--> {{Isotopes table |symbol=W |refs=NUBASE2020, AME2020 II,<!-- upated 2025-03-08 --> IsotopeFRIB, IsomerFRIB |notes=m, unc(), mass#, hl#, hl-nst, spin(), spin#, daughter-st, daughter-nst, A, B+, B-, EC, IT, discoveryname }} |-id=Tungsten-156 | ¹⁵⁶W<ref name=Os160>{{cite journal |first1=A.
