1.	Following electron capture: a. The number of protons increases b. The atom is negatively charged c. The atomic mass stays the same d. The atomic number is reduced e. Bremsstrahlung radiation is released
Answer» a. False. A radionuclide with a neutron deficit may increase its number of neutrons by capturing an electron from the K-shell, which combines with a proton to form a neutron. b. False. The neutron (no charge) is formed from the combination of a negative electron and a positive proton, leaving no net change in the charge. c. True. The conversion of a proton to a neutron results in the atomic mass being conserved. d. True. Atomic number is equal to the number of protons. e. False. The daughter nuclide emits characteristic X-ray radiation as a result of an electron from an outer shell filling the vacancy in the K-shell.
