Naturally occurring chromium (₂₄Cr) is composed of four stable isotopes; ⁵⁰Cr, ⁵²Cr, ⁵³Cr, and ⁵⁴Cr with ⁵²Cr being the most abundant (83.789% natural abundance). Twenty-two radioisotopes, all synthetic, have been characterized, the most stable being ⁵¹Cr with a half-life of 27.70 days. All of the remaining radioactive
