Chemistry Principles of Modern Chemistry The americium isotope 241 Am is used in smoke detectors. Describe the composition of a neutral atom of this isotope for protons, neutrons, and electrons. The americium isotope 241 Am is used in smoke detectors.
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. This turns the neutron into a proton, and changes the Plutonium-241 into Americium-241. Now armed with 95 protons and 146 neutrons, Americium-241 goes down another decay pathway. AMERICIUM .
