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.

Americium-241 is comprised of: 95 protons. 146 neutrons. 95 electrons (assuming no charge) *** Therefore, 95 protons * (1.007276u) + 146 neutrons * (1.008664u) + 95 electrons * (0.00054858u) = 243.00828u, which is the "predicted" mass. The isotope mass of Americium-241 is 241.056829144u. Therefore, the mass defect is 243.00828u - 241.056829144u 242 Cm 96. Its longest lived isotopes are 243 Am, with a half-life of 7370 years, 241 Am with a half-life of 432.2 years and 242 Am with a half-life of 141 years. The number of electrons in each of Americium's shells is 2, 8, 18, 32, 25, 8, 2 and its electron configuration is [Rn] 5f 7 7s 2.The americium atom has a radius of 173.pm and its Van der Waals radius is 244.pm.

The mass number of an atom is the sum of the number of protons, neutrons, and electrons it contains. The nucleus of an atom contains its protons and neutrons, and is positively charged. The atomic number of an atom is the number of protons it contains. Electrons reside outside the nucleus in what is called the electron cloud.

Number of Neutrons. 148. Number of Electrons. 95.

None of the above Which of the following statements correctly describes the responses of protons, neutrons, and electrons in a magnetic or electrical field? A. Protons and electrons are deflected in opposite directions, but neutrons show no … Americium was first made late in 1944 at the University of Chicago by a team which included Glenn Seaborg, Ralph James, Leon Morgan, and Albert Ghiorso. The americium was produced by bombarding plutonium with neutrons in a nuclear reactor. This produced isotope americium-241, which has a half-life of this is 432 years.

americium-241 (used in smoke alarms) is a deca Nov 5, 2016 Americium-241 was directly obtained from plutonium upon absorption of one neutron. A thorium atom has 90 protons and therefore 90 electrons, of which Thorium-232 (232Th), which has 142 neutrons, is the most stable& (a) 25 protons, 20 neutrons, 24 electrons. (b) 45 protons, 24 neutrons, 43 electrons (a) berkelium-244, made by the reaction of Am-241 and He-4. the extremely small mass of the electron compared to the mass of a proton.

It was produced by irradiating plutonium with neutrons during the Manhattan Project. A. Protons and electrons are deflected in opposite directions, but neutrons show no response. B. Only protons are deflected, but neutrons and electrons are not affected.
