1.	Regarding radioactive decay: a. K-electron capture is a type of radioactive decay process b. It is a stochastic process c. It can occur following an increase in electron numbers d. It results in absorption of energy from the surrounding atoms e. It always results in a stable daughter nucleus
Answer» a. True. Neutron deficient radio nuclides increase their number of neutrons relative to protons by capturing an electron from the K-shell. b. True. c. False. Radioactive decay occurs due to the nuclei being unstable as a result of either an excess or a deficiency in the number of neutrons or protons. d. False. Radioactive decay is not an energy-dependent process and occurs independently. e. False. Although radioactive decay can result in a stable daughter nucleus, a metastable or unstable daughter nucleus may also be formed.
