84 218Po: 84 signifies the number of protons; 218 is the atomic mass (#protons + #neutrons)
When a beta particle is emitted, one neutron gets changed to a proton, so if 84 218 Po emits a beta particle, the number of protons will go up by one (atomic number = 85), and the atomic mass will stay the same.
When the polonium emits an alpha particle, it emits 2 protons and 2 neutrons: 82 is the atomic number, and 216 is the atomic mass
