What we mean is that Thorium-232 decays into Radium-228 plus an alpha particle. That isotope of Radium subsequently decays into Actinium-228 via beta decay, and so on until Lead-208 is the final end product. Name: Thorium: Symbol: Th: Atomic Number: 90: Atomic Mass: 232.038 atomic mass units: Number of Protons: 90: Number of Neutrons: 142: Number of Electrons: 90: Melting Thus alpha emission lowers the atomic number (number of protons) by two units, the neutron number by two units, and the mass number (total of neutrons and protons) by four units. At the head of the thorium series, for example, thorium-232 undergoes alpha decay to radium-228.
