What is the nuclear decay equation for bismuth-213?
213Bi --> 209Tl + 4He, 213Po + e- 209Tl --> 209Pb + e- 213Po --> 209Pb + 4He 209Pb --> 209Bi + e- 209Bi --> 205Tl + 4He 205Tl, stable
If the isotope bismuth-213 emits an alpha particle two protons and two neutrons which element will be left over?
Lead-209 will be left over after the isotope bismuth-213 undergoes alpha decay, as the emission of an alpha particle causes the atomic number of the element to decrease by 2. Bismuth-213 has an atomic number of 83, so after the emission of an alpha particle (which has an atomic number of 2), the resulting element will have an atomic number of 81, which corresponds to lead.
What is the equation for Plutonium-241 decay?
A:Uranium - 238 --> Pb - 206 + Alpha + Beta note this is a simplified over all reaction, the actual process involves around 15 steps...A:The equation for the alpha decay of 238U is: 92238U --> 90234Th + 24HeThe alpha particle is represented as an He nucleus.
Tell you all about actinium?
Actinium (pronounced /ækˈtɪniəm/) is a chemical element in the periodic table that has the symbol Ac and atomic number 89. Notable characteristics Actinium is a silvery, radioactive, metallic element. Due to its intense radioactivity, Actinium glows in the dark with a pale blue light. It is found only in traces in uranium ores as 227Ac, an α and β emitter with a half-life of 21.773 years. One ton of uranium ore contains about a tenth of a gram of actinium. Applications It is about 150 times as radioactive as radium, making it valuable as a neutron source. Otherwise it has no significant industrial applications. 225Ac is used in medicine to produce 213Bi in a reusable generator or can be used alone as an agent for radio-immunotherapy for Targeted Alpha Therapy (TAT). 225Ac was first produced artificially by the ITU in Germany using a cyclotron and by Dr Graeme Melville at St George Hospital in Sydney using a linac in 2000. History Actinium was discovered in 1899 by André-Louis Debierne, a French chemist, who separated it from pitchblende. Friedrich Oskar Giesel independently discovered actinium in 1902 and called it "emanium" in 1904. Debierne's name was retained because it had seniority. The chemical behavior of actinium is similar to that of the rare earth lanthanum. The word actinium comes from the Greek aktis, aktinos, meaning beam or ray. Occurrence Actinium is found in trace amounts in uranium ore, but more commonly is made in milligram amounts by the neutron irradiation of 226Ra in a nuclear reactor. Actinium metal has been prepared by the reduction of actinium fluoride with lithium vapor at about 1100 to 1300ºC. Isotopes Naturally occurring actinium is composed of 1 radioactive isotope; 227Ac. 36 radioisotopes have been characterized with the most stable being 227Ac with a half-life of 21.772 y, 225Ac with a half-life of 10.0 days, and 226Ac with a half-life of 29.37 h. All of the remaining radioactive isotopes have halctinium (pronounced /ækˈtɪniəm/) is a chemical element in the periodic table that has the symbol Ac and atomic number 89. Precautions 227Ac is extremely radioactive, and in terms of its potential for radiation induced health effects, 227Ac is even more dangerous than plutonium. Ingesting even small amounts of 227Ac would be fatalctinium (pronounced /ækˈtɪniəm/) is a chemical element in the periodic table that has the symbol Ac and atomic number 89.
