We are asked what is the daughter nucleus produced when fluorine-18 decays by positron emission
Recall that in a nuclear reaction, the number of protons and neutrons are affected and the identity of the element changes. For Positron emission: forms a positron particle (01e, atomic mass = 0, atomic number = 1)
The incomplete nuclear equation is:
189F → ___ + 01e,
Atomic mass of the daughter nuclide:
18 = x + 0
x = 18 – 0 = 18
Identify the nuclide produced when fluorine-18 decays by positron emission: 189F → 01e + ? Express your answer as an isotope using prescripts.
