WebChapter 31.2 - Nuclear Physics Uranium-238 (238.050788 u) undergoes alpha decay into Thorium-234 (234.043601 u). Assume all of the energy released is in the form of kinetic energy of the alpha particle, ignoring any motion of the U-238 or Th-234 nuclei. Find the speed of the alpha particle (4.002602 u). WebUranium-238 undergoes alpha decay to become thorium-234. (The numbers following the chemical names refer to the number of protons plus neutrons.) In this reaction, uranium-238 loses two protons and two neutrons to become the element thorium-234.

WebIn this beta decay, a thorium-234 nucleus has one more proton than the original nucleus. In this beta decay, a thorium-234 nucleus has become a protactinium-234 nucleus. When … WebMar 17, 2009 · The mass number of thorium-234 is 234; the Atomic Mass is 234,043601(4). WebAug 15, 2024 · Similarly, Thorium-234 having an atomic number of 90 will have an amount of neutrons equal to: 234 - 90 = 144 neutrons. Let's compare the difference between U-238 and Th-234: Protons: 92 → 90 Neutrons: 146 → 144 Therefore, for U-238 to transform to Th-234, it must give off 2 protons and 2 neutrons. cigarettes online delivery
