This concerns both nuclear theory and . Which force is stronger? But uranium doesn't deserve it's image as one of the periodic table's nasties. The alpha particle is initially at rest at the surface of the thorium nucleus, which is 15 fm in diameter. However, it does not fully account for the additional, and more significant interplay between multiple electrons and nuclei that occur in multi-electron atoms. 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). It only takes a few minutes.
