Polonium-210 (210 8 Po) has an atomic mass of 209.982848 u and decays via the emission of an .. particle to Lead-206 (2068,Pb) which has an atomic mass of 205.974440 u. Mass numbers of typical isotopes of Polonium are 208-210. Atomic Number of Polonium. Read More death of Arafat Radioactive isotope of polonium; mass 210, half-life 140 days, α-radiation; used to calibrate radiation counters, and in oil well logging and atomic batteries. Polonium is a chemical element with atomic number 84 which means there are 84 protons and 84 electrons in the atomic structure. Name: Atomic Mass The isotope polonium-217 (Z=84, mass = 217.006336 u) can decay by alpha emission and also by beta-minus emission. Polonium-210 (the isotope of Polonium with Atomic Weight of 210; since the Atomic Number of Polonium is 84, meaning it has 84 protons and 84 electrons orbiting around its nucleus, we know that it must have 210 – 84 = 126 neutrons) is unstable and emits very weak gamma rays.
