Best Answers

The Element Chromium - Known Isotopes. ... from the National Nuclear Data Center. Please visit their site for more information. Isotopes With A Known Natural Abundance. Mass Number, Natural Abundance, Half-life. 50, 4.345%, > 1.3×10 +18 years. 52, 83.789%, STABLE. 53, 9.501%, STABLE. 54, 2. read more

The stable isotopes of chromium have masses of 50, 52, 53 and 54. The Cr isotope at mass 51 has a half life of 30 days by electron capture decay. This is the right place to mention the work of nuclear chemists. read more

This element also has 2 meta states, 45m Cr, the more stable one, and 59m Cr, the least stable isotope or isomer. 53 Cr is the radiogenic decay product of 53 Mn. Chromium isotopic contents are typically combined with manganese isotopic contents and have found application in isotope geology. read more

There have also been 22 radioactive (unstable) isotopes of chromium discovered and all of these have been synthetically created. The most stable of these isotopes is 51 Cr, with a half life of 27.7 days. read more
