Question
Multiple Choice QuestionAlpha decay produces a new isotope with a mass number that is less than the that of the parent isotope by ______.Multiple choice question.2431
Solution
The correct answer is 4. In alpha decay, an atomic nucleus emits an alpha particle. An alpha particle is identical to the nucleus of a helium-4 atom, which consists of 2 protons and 2 neutrons. Therefore, the mass number of the new isotope is less than that of the parent isotope by 4.
