All known calcium isotopes (from Ca-34 to Ca-58) <br /><br />Calcium has a lot of isotopes, many of which are radioactive and obtained artificially. <br />5 isotopes are stable and found in nature. <br />Calcium-40 is the most common calcium isotope its retention from total calcium is 96%. <br />The longest-lived radioactive calcium isotope is calcium-48, which has a half-life of 6.4 billion billion years, but many radioactive isotopes calcium have a half-life of less than 1 second <br /><br />#calcium #isotopes #Artificialisotopes #Calciumisotopes #Radioactiveisotopescalcium #Stableisotopescalcium #isotope #physics
