a chemical element, atomic number 95, atomic weight 243. (See Appendix 6.)

am·er·i·ci·um (Am),

(am'ĕ-ris'ē-ŭm),
An element obtained by the bombardment of uranium with neutrons or β decay of plutoniums 241, 242, and 243; atomic no. 95; atomic weight 243.06. 241Am (half-life of 432.2 years) has been used in the diagnosis of bone disorders. 243Am has a half-life of 7370 years.
