varieties of the element, called "isotopes," may have different numbers of neutrons. so, an atom of hydrogen will always have one proton, but can have one, two, or even three neutrons. radioactive isotopes, or radioisotopes, are isotopes of an element having an unstable nucleus that decays (emitting alpha
, beta, or gamma rays) until stability is reached. the stable end product is a nonradioactive isotope of another element. uranium (u) is a metallic, silver-gray element that is a member of the actinide series. the radioisotope uranium- has more neutrons than uranium and decays to lead- . since small...
