Thorium 234 atomic number

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.
