But, in another aspect, americium-241 is not ideal for demonstrating the characteristics of alpha Americium - Mass Number - Neutron Number - Am. Mass numbers of typical isotopes of Americium are 241-243. The total number of neutrons in the nucleus of an atom is called the neutron number of the atom and is given the symbol N. Americium-241 is used in smoke detectors as an alpha source. Write the balanced equation for an alpha particle emission from americium. Ionization smoke detectors usually use a radioisotope, typically americium-241, to ionize air and to detect smoke. In this case americium-241 decays to neptunium-237 and is, in fact, a member of neptunium series. Types of Decay in Neptunium Series.

Americium-243 and 241-Am, alpha emitters, are the longest lived with half-lives of 7,380 years and 432.7 years, respectively. Americium-241 and 243-Am also undergo spontaneous fission. Americium-242m has a half-life of 141 years, and the half-lives of the remaining isotopes are measured in hours, minutes, or seconds.
