Which graph below illustrates electron capture?

Question

Quizplus · Accepted Answer

In electron capture, an electron from the inner shell is captured by the nucleus, resulting in the emission of a neutrino. This causes a decrease in the atomic number, and an increase in the neutron-to-proton ratio. In graph III, we see a decrease in the atomic number (Z) and an increase in the neutron-to-proton ratio, which indicates electron capture. The other graphs do not show these characteristics.
