Naturally occurring scandium Sc is composed of one stable isotope sup 45 sup Sc. Twenty four radioisotope s have been characterized with the most stable being sup 46 sup Sc with a half life of 83.8 days, sup 47 sup Sc with a half life of 3.35 days, and sup 48 sup Sc with a half life of 43.7 hours. All of the remaining radioactive isotopes have half lives that are less than four hours, and the majority of these have half lives that are less than two minutes, the least stable being sup 39 sup Sc with a half life shorter than 300 nanoseconds. The half lives for isotopes with mass numbers less than 39 is unknown. This element also has 10 meta state s with the most stable being sup 44m sup Sc t sub sub 58.6 h . The isotopes of scandium range in atomic weight from 36 atomic mass unit u sup 36 sup Sc to 60 u sup 60 sup Sc . The primary decay mode at masses lower than the only stable isotope, sup 45 sup Sc, is beta decay Beta plus or electron capture , and the primary mode at masses above it is beta minus. The primary decay product s at atomic weights below sup 45 sup Sc are calcium isotopes and the primary products from higher atomic weights are titanium isotopes.
