Problem
Consider the ion 919F− and the neutral isotope 918F.
Respond to each of the following prompts. Show all reasoning and explicitly indicate units where appropriate.
(a) For 919F−, determine (i) the number of protons, (ii) the number of neutrons, and (iii) the number of electrons.
(b) For the neutral isotope 918F, determine the number of protons, neutrons, and electrons.
(c) State whether the two nuclides described above are isotopes, ions of the same isotope, or entirely different elements. Justify your answer based on nuclear and electronic composition.
