Question

what are radioactive isotopes applications of radioactive isotopes​

Answer 1

Answer:

A radioactive isotope, also known as a radioisotope, radionuclide, or radioactive nuclide, is any of several species of the same chemical element with different masses whose nuclei are unstable and dissipate excess energy by spontaneously emitting radiation in the form of alpha, beta, and gamma rays.

Radioactive isotopes have many useful applications. In medicine, for example, cobalt-60 is extensively employed as a radiation source to arrest the development of cancer. Other radioactive isotopes are used as tracers for diagnostic purposes as well as in research on metabolic processes.

Answer 2

i) Isotopes are elements with the same atomic number but different mass numbers. Example, hydrogen has 3 isotopes - protium (1H1), deuterium (2H1) and tritium (3H1).

ii) Isobars are elements which have different atomic numbers but the same mass number. They are different chemical elements. Example, iron and nickel, both have mass number 58, whereas atomic numbers are different.  

⇒ Uses of isotopes -

a) The radioisotopes are being widely used in the field of agriculture than in any other field of science and their application is leading us to the solution of many agriculture problems in a shorter time and more precisely. Thus, radioisotopes have become a very important aid to scientists dealing with the solution of agricultural problems. In addition to this, radioactive tracers and radiation sources have become indispensable to all the intricate agricultural research problems
