Question

Quizplus · Accepted Answer

In alpha decay, an alpha particle (which consists of 2 protons and 2 neutrons) is emitted. This decreases the atomic number by 2 and the mass number by 4. For $^{144}_{60}$Nd, the resulting isotope will have an atomic number of 58 and a mass number of 140, which corresponds to $^{140}_{58}$Ce.
