Physical properties
All the isotopes of americium belonging to the transuranic subseries of the actinide seriesare radioactive and are artificially produced. Americium has similar chemical and physicalcharacteristics and is homologous to europium, located just above it in the rare-earth (lanthanide)series on the periodic table. It is a bright-white malleable heavy metal that is somewhatsimilar to lead. Americium’s melting point is 1,176°C, its boiling point is 2,607°C, and itsdensity is 13.68g/cm3.

Uses
Gamma radiography, radiochemical research, diagnostic aid, electronic devices. Americium-141, with a half-life of 432 years, which produces both alpha (helium nuclei)and gamma rays (somewhat like X-rays), has found some commercial uses. One use is as thedetector used in household smoke alarms The americium-141 isotope emits alpha particlesthat ionize air by removing electrons from the molecules of air and improving its electricalconductivity. Smoke reduces this conductivity, thus triggering the alarm. Another use is americium-241’s high-energy gamma rays in radiography, in which portable X-ray instruments caneasily be transported for emergency use. As a gamma ray source, americium-241 is used as adiagnostic aid to check the quality of welds in metals.
