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) Atoms with unstable nuclei are called nuclides and atoms with stable nuclei are called isotopes.
(2) In radioactive decay, a radionuclide is transformed into the nuclide of another element.
(3) The magnitude of the decay rate for a radionuclide is a function of the nuclide's temperature.

(1) is FALSE because the terms "nuclide" and "isotope" do not distinguish between stability; a nuclide is any species of atom, regardless of stability, and isotopes are variants of elements with different neutron numbers. (2) is TRUE as radioactive decay indeed transforms a radionuclide into another element's nuclide. (3) is FALSE because the decay rate of a radionuclide is not a function of temperature; it is a constant property for each radionuclide.
