What happens to Radon if it has a -Atomic Number of 88 -Nuclear Mass of 226 -If it emits Alpha Radiation?

-Since an Alpha Particle has 2 Neutrons and 2 Protons... -Then Minus 2 From the Radon Atomic Number -And Minus 4 From the Radon Atomic Mass -Therefore making This Equation: Ra --> Rn [222 AM, 86 AN] + a [4 AM, 2 AN]
