When an alpha particle is emitted, the element Polonium 214 is formed because an alpha particle is essentially a helium nucleus consisting of 2 protons and 2 neutrons. This causes the original element to lose 2 protons and 2 neutrons, resulting in the formation of Polonium 214. On the other hand, when a beta particle is emitted, the element Astatine 218 is formed because a beta particle is an electron emitted from the nucleus during radioactive decay. This causes a neutron to convert into a proton, leading to the formation of a new element with an increased atomic number. **
