It transforms (or decays) into an atom with an atomic number 2 less and a mass number 4 less. Thus, radium-226 decays through α-particle emission to form radon-222 according to the equation: 226 88 Ra → l222 86 Rn +l4 2He therefore the alpha decay product of Ra-226 is Rn-222 when a nucleus undergoes beta decay, a neutron converts to a proton and emits an electron the atomic mass remains the same since the sum of 226Ra LNHB – M.M. Bé, V. Chisté December 2003 INEEL/ R.G. Helmer 226Ra - Comments on evaluation of decay data by M.M. Bé, V. Chisté Ra-226 disintegrates by alpha emissions to excited levels and to the ground state of Rn-222. The alpha emission intensities were measured only once (Bastin-Scoffier) and the results were When radium-226 (Ra-226) undergoes alpha emission, a daughter nucleus which has 2 protons and 4 neutrons will be produced, accompanied by the See full answer below. Become a member and unlock An example of alpha decay is the historically important transformation of radium 226 into radon 222 through the emission of an alpha particle. This reaction releases 4.6 MeV, and leaves behind a radioactive noble gas (radon), which is what allowed Rutherford to observe the process in Montreal in 1898. More specifically, natural radium (which is mostly 226 Ra) emits mostly alpha particles, but other steps in its decay chain (the uranium or radium series) emit alpha or beta particles, and almost all particle emissions are accompanied by gamma rays.
