Isotopes of vanadium

Naturally occurring vanadium (₂₃V) is composed of one stable isotope, ⁵¹V, and one radioactive isotope, ⁵⁰V, with a half-life of 2.71×10¹⁷ years. Twenty-five artificial radioisotopes have been characterized, ranging from ⁴²V to ⁶⁸V. The most stable of these are ⁴⁹V with a half-life of 330 days and ⁴⁸V 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 ⁶⁰V.

The primary decay mode before the most abundant stable isotope ⁵¹V is electron capture or positron emission resulting in titanium isotopes; that after the beta decay to chromium isotopes.
