{{Short description|none}} {{Infobox vanadium isotopes}} Naturally occurring vanadium (<sub>23</sub>V) is composed of one stable isotope, <sup>51</sup>V, and one radioactive isotope, <sup>50</sup>V, with a half-life of {{val|2.71|e=17}} years. Twenty-five artificial radioisotopes have been characterized, ranging from <sup>43</sup>V to <sup>68</sup>V. The most stable of these are <sup>49</sup>V with a half-life of 330 days and <sup>48</sup>V with a half-life of 15.9735 days. All of the remaining radioactive isotopes have half-lives shorter than an hour, with the majority of them below 10 seconds. Seven metastable excited states have also been observed, two of which are for <sup>60</sup>V.
The primary decay mode before the most abundant stable isotope <sup>51</sup>V is electron capture or positron emission resulting in titanium isotopes; that after the beta decay to chromium isotopes.
