When 92U nuclides are bombarded with neutrons, one of the many fission reactions that it can undergo is the following (shown in the adjacent image): baryon number 4 & charge +2 ? A uranium nucleus (mass 238u, charge 92e) decays, emitting an alpha particle (mass 4u, charge 2e) and leaving a thorium nucleus (mass 234u, charge 90e). Solution for A uranium nucleus emits an α particle. If it loses 2 protons and 2 neutrons, it will then have 90 protons and 144 neutrons. The radius of the uranium nucleus is approximately 7.4 x 10^-15 meters What is the electric field this nucleus produces just outside its surface? However, forces in the nucleus counteract this repulsion and hold the nucleus together. So that means Uranium is going to lose two protons and 2 neutrons. If the nucleus is unstably large, it will emit a 'package' of two protons and two neutrons called an alpha particle. An example of a nucleus that undergoes alpha decay is uranium-238. The nuclear density for a typical nucleus can be approximately calculated from the size of the nucleus and from its mass. See also: Mass Number. The 92 protons of the uranium nucleus must be conserved, and complementary fission-product pairs—such as krypton-36 with barium-56, rubidium-37 with cesium-55, or strontium-38 with xenon-54—would be possible.
