When the radioactive nuclide ¹⁹⁸Po undergoes alpha emission,what is the product nuclide?

Question

Quizplus · Accepted Answer

Alpha emission involves the release of an alpha particle, which is equivalent to a helium nucleus (2 protons and 2 neutrons). This results in the decrease of the atomic number by 2 and the mass number by 4. Therefore, for the nuclide ¹⁹⁸Po, the product nuclide would have an atomic number of 118 - 2 = 116 and a mass number of 298 - 4 = 294, which corresponds to ¹⁹⁴Pb.
