More Chemistry
All atomic nuclei of the chemical element vanadium are summarized under vanadium isotopes; these all consist of an atomic nucleus with 23 protons and, in the uncharged state, 23 electrons. The difference between each vanadium isotope is based on the number of neutrons in the nucleus.
Vanadium occurs naturally in the form of a mixture of the stable isotope V-51 and the radioisotope V-50:
