actinium

World Encyclopedia | 2005 | © World Encyclopedia 2005, originally published by Oxford University Press 2005. (Hide copyright information) Copyright

actinium (symbol Ac) Radioactive, metallic element, the first of the actinide series, discovered (1899) by French chemist André Debierne.It is found associated with uranium ores. Ac227, a decay product of U235, emits beta particles during disintegration. Properties: at.no.89; r.d.10.07; m.p. 1100°C (1900°F); b.p. 3200°C (5800°F); most stable isotope Ac227 (half-life 21.8 yr).
