In medical imaging, iodine-123 is often used to detect abnormalities in the thyroid because of its affinity toward that organ. The imaging device detects the neutrinos emitted during electron capture by iodine-123:

(a) How much charge is accumulated during this reaction?

(b) How many neutrinos are emitted if 2 mg of iodine-123 is given to a patient?
