What makes lead 208 emit an alpha particle?
Alpha radiation. Explanation: Polonium-212 undergoes alpha decayto produce lead-208, which means that it gives off alpha radiation, i.e. alpha particles. An alpha particle, #alpha#, is simply the nucleus of a helium-4 atom, which means that it contains two protons two neutrons When a radioactive nuclide emits an alpha particle
