Uranium-235 is a rare isotope of uranium that can be used for power plants as well as bombs. Its nucleus decays to a thorium-231 nucleus by emitting an α-particle. Uranium has atomic number 92, and thorium has atomic number 90. A nuclear reaction such as this is written using the following notation: 235U → 231Th + α Mass number is the number of protons plus the number of neutrons. It is the top number in this notation. In these nuclear...
