Question

Polonium (Po) decays by alpha emission. What will be the mass number, atomic number, and symbol of the new atom produced by the alpha decay of Po? Choose 3 correct statements that tell the correct atomic number, mass number and symbol of the daughter atom. If you are unsure how to solve an alpha decay problem, see the example linked HERE. Periodic Table Link a The atomic number of the new daughter atom will be 82. b The atomic number of the new daughter atom will be 86. c The atomic number of the new daughter atom will be 208. d The mass number of the new daughter atom will be 216. e The mass number of the new daughter atom will be 208. f The mass number of the new daughter atom will be 86. g The symbol of the new daughter atom is Rn. h The symbol of the new daughter atom is Pb.
