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. 24 artificial radioisotopes have been characterized (in the range of mass number between 40 and 65) with the most stable being 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, the majority of them below 10 seconds, the least stable being ⁴²V with a half-life shorter than 55 nanoseconds, with all of the isotopes lighter than it, and none of the heavier, have unknown half-lives. In 4 isotopes, metastable excited states were found (including 2 metastable states for ⁶⁰V), which adds up to 5 meta states.

The primary decay mode before the most abundant stable isotope ⁵¹V is electron capture. The next most common mode is beta decay. The primary decay products before ⁵¹V are element 22 (titanium) isotopes and the primary products after are element 24 (chromium) isotopes.

^ ^mV – Excited nuclear isomer.

^ ( ) – Uncertainty (1σ) is given in concise form in parentheses after the corresponding last digits.

^ # – Atomic mass marked #: value and uncertainty derived not from purely experimental data, but at least partly from trends from the Mass Surface (TMS).

^ Bold half-life – nearly stable, half-life longer than age of universe.

^ ^a ^b ^c # – Values marked # are not purely derived from experimental data, but at least partly from trends of neighboring nuclides (TNN).

^ Modes of decay:

EC:	Electron capture
IT:	Isomeric transition
p:	Proton emission

^ Bold symbol as daughter – Daughter product is stable.

^ ( ) spin value – Indicates spin with weak assignment arguments.
