Characterize EACH of the three given statements as being TRUE or FALSE and then indicate the collective true-false status of the statements using the choices: (1) The final product in a radioactive decay series is always a stable nuclide.
(2) The most important fissionable radionuclide is uranium-238.
(3) Beta particles have a charge of -1 and have no mass.

Question

Quizplus · Accepted Answer

1) True: Radioactive decay series end with the formation of a stable nuclide, typically a form of lead for heavy elements. 2) False: The most important fissionable radionuclide is uranium-235, not uranium-238. Uranium-238 is fertile, meaning it can be converted into a fissionable material (plutonium-239) in a reactor, but it is not the primary fuel for nuclear reactors. 3) False: While beta particles do have a charge of -1, they do have mass, albeit very small (they are high-energy electrons or positrons).
