In an artificial transmutation process,a nucleus of Al-27 absorbs a neutron,emits an alpha particle,and is converted into a new nuclide.What is the new nuclide formed?

Question

Quizplus · Accepted Answer

When Al-27 absorbs a neutron, its mass number becomes 28 (27 + 1). After emitting an alpha particle (which has a mass number of 4), the new mass number is 24 (28 - 4). The atomic number of Al (13) decreases by 2 (because an alpha particle also has 2 protons), resulting in an atomic number of 11, which corresponds to sodium (Na). Therefore, the new nuclide is Na-24.
