what are isotopes and radioactive isotopes ???
Answers
Answer:
Isotopes are variants of a particular chemical element which differ in neutron number, and consequently in nucleon number. ... Each atomic number identifies a specific element, but not theisotope; an atom of a given element may have a wide range in its number of neutrons.
Radioisotopes are radioactive isotopes of an element. They can also be defined as atoms that contain an unstable combination of neutrons and protons, or excess energy in their nucleus.
Explanation:
A Radioisotope is also an isotope by nature. The difference is that radioisotopes are very unstable and contain high levels of nuclear energy and emit this energy in the form of nuclear radiation. Main difference: Isotopes can be stable or unstable, but Radioisotopes are always unstable.
