Determine the identity of the daughter nuclide from the electron capture by Fe.

Question

Quizplus · Accepted Answer

Electron capture involves the capture of an electron by the nucleus, which combines with a proton to form a neutron. In this case, the parent nuclide is Fe-11 (iron-11), which has 26 protons and 11 neutrons. Electron capture by Fe-11 would result in the loss of a proton and the gain of a neutron, forming a new nuclide with one fewer proton and one more neutron. The only option that fits this description is Mn-11 (manganese-11), which has 25 protons and 11 neutrons, so the correct answer is B.
