Question

Determine the identity of the daughter nuclide from the positron emission of  Ge.

Quizplus · Accepted Answer

Positron emission occurs when a proton in the nucleus is converted into a neutron and a positron, which is emitted from the nucleus. The atomic number of the parent nucleus decreases by one, while the mass number remains the same.

In this case, the parent nucleus is 11 Ge, which has an atomic number of 32. Therefore, after undergoing positron emission, the daughter nucleus will have an atomic number of 31.

The only option that corresponds to an element with an atomic number of 31 is gallium (Ga), which is choice E. Therefore, the correct answer is E.
