QUESTION 4 Write the balanced nuclear reaction for the decay of uranium-238 to thorium-234. ОА. 23...
(1 point) A Uranium-238 nucleus (U-238) decays to a Thorium-234 (Th234) by emitting an alpha particle (i.e. a Helium-4 nucleus): 1,228 +Th%d4 + He A Uranium nucleus has 92 protons in it while a Helium nucleus has 2 protons. The mass of a Helium nucleus is 6.645 x 10-27 kg. For this problem assume that the Uranium nucleus is initially at rest and the Thorium nucleus remains at rest after the decay. If the alpha particle is initially at rest...
