What is the definition of a radioisotope?A.A nonradioactive isotope of an elementB.A radioactive isotope of an elementC.Any one of the isotopes of an elementD.Any particle emitted by radioactive decay

What does radioactive mean?A.Generating positively or negatively charged ionsB.Having electron transitions at radio-wave frequenciesC.Emitting radiation as a result of unstable nucleiD.Absorbing high-energy electromagnetic radiation

Radio activity is the process by which a nucleus of an unstable atom loses energy by emitting ionizing radiation. A material that spontaneously emits this kind of radiations which includes a, b, g rays is considered radioactive.The positively charged particle with 2 units of relative of charge and 4 units of mass isSelect an answerABCDpositron
