OpenStudy (anonymous):
Alpha particle has 4 nucleons and 2 protons, hence if 213 Bi undergoes alpha decay, it means it loses it. Hence the nucleon number becomes 213-4= 209. According to the periodic table, the new element is Po.
OpenStudy (anonymous):
so 209 is the mass number and it goes on the top and 84 is the number of protons and it goes on the bottom right
