Final answer:
Electron capture by oxygen-15 (15O) results in the formation of nitrogen-15 (15N) and a neutrino. The energy released during this process can be found using the mass-energy equivalence formula but requires specific mass values to perform an exact calculation.
Step-by-step explanation:
Electron capture is a process in which a proton-rich nuclide absorbs an inner atomic electron, thereby transforming a proton into a neutron and emitting a neutrino. The equation for electron capture by oxygen-15 (15O) is:
15/8 O + e− → 15/7 N + νε
The energy released during this process can be calculated using the mass difference between the reactants and products multiplied by the square of the speed of light (E = δm c²). Without specific mass values provided, we cannot perform an exact calculation, but in general, the energy released in nuclear reactions is typically in the order of millions of electron volts (MeV).
