{{Main|Isotopes of molybdenum}}
There are 39 known [[isotopes]] of molybdenum, ranging in [[atomic mass]] from 81 to 119, as well as 13 metastable [[nuclear isomer]]s. Seven isotopes occur naturally, with atomic masses of 92, 94, 95, 96, 97, 98, and 100. Of these naturally occurring isotopes, only molybdenum-100 is unstable.{{NUBASE2020|ref}}

Molybdenum-98 is the most [[isotopic abundance|abundant]] isotope, comprising 24.14% of all molybdenum. Molybdenum-100 has a [[half-life]] of about 10<sup>19</sup>&nbsp;[[year|y]] and undergoes [[double beta decay]] into ruthenium-100. All unstable isotopes of molybdenum decay into isotopes of [[niobium]], [[technetium]], and [[ruthenium]]. Of the [[synthetic radioisotope]]s, the most stable is <sup>93</sup>Mo, with a half-life of 4,839 years.<ref name="93Mo"/>

The most common isotopic molybdenum application involves [[molybdenum-99]], which is a [[fission product]]. It is a [[parent radioisotope]] to the short-lived gamma-emitting daughter radioisotope [[technetium-99m]], a [[nuclear isomer]] used in various imaging applications in medicine.<ref name="armstrong">{{cite magazine|author=Armstrong, John T.|url=http://pubs.acs.org/cen/80th/technetium.html|title=Technetium|magazine=Chemical & Engineering News|date=2003|access-date=2009-07-07|archive-url=https://web.archive.org/web/20081006002652/http://pubs.acs.org/cen/80th/technetium.html|archive-date=2008-10-06|url-status=live}}</ref>
In 2008, the [[Delft University of Technology]] applied for a patent on the molybdenum-98-based production of molybdenum-99.<ref>Wolterbeek, Hubert Theodoor; Bode, Peter [https://archive.today/20130122082910/http://worldwide.espacenet.com/publicationDetails/biblio?DB=EPODOC&adjacent=true&locale=nl_NL&FT=D&date=20110330&CC=EP&NR=2301041A1&KC=A1 "A process for the production of no-carrier added 99Mo"].
