Atoms are composed of three main subatomic particles: protons, neutrons and Smoke detectors contain Americium-241, an artificially produced radioactive
It is an Actinoid Metal with the symbol Am. Americium was the fourth synthetic element to be discovered in 1944 by Seaborg, James and Morgan. Americium-241 is also used to measure the thickness of materials. For instance, a small piece of americium-241 can be placed above a conveyor belt carrying newly made glass. A Geiger counter, a device for counting alpha radiation, is placed below the conveyor belt.

Americium-241 (241 Am) is an isotope of americium.Like all isotopes of americium, it is radioactive. 241 Am is the most common isotope of americium.It is the most prevalent isotope of americium in nuclear waste.Americium-241 has a half-life of 432.2 years. It is commonly found in … What is Americium. Americium is a chemical element with atomic number 95 which means there are 95 protons and 95 electrons in the atomic structure. The chemical symbol for Americium is Am.. Americium is a transuranic member of the actinide series, in the periodic table located under the lanthanide element europium, and thus by analogy was named after the Americas.

A Geiger counter, a device for counting alpha radiation, is placed below the conveyor belt. same number of protons in the nucleus but a different number of neutrons.) Americium-241 was first produced in 1944 in a nuclear reactor at the University of Chicago. Dr. Glenn Seaborg gave the new element its name in 1946 in honor of the continent on which it was discovered.
