Question

Name the isotope of hydrogen which is Radioactive.

Answer 1

Hint: In the given question radioactive isotope of hydrogen has been asked. Though the hydrogen \[\left( {1H} \right)\]has the three number of naturally occurring isotopes, which are denoted as 1H, 2H, and 3H. as Hydrogen is the individual element whose isotopes have different names in common use today.

Complete step-by-step answer :
Radioactive isotope, also termed as radioactive nuclide or radioisotope or radionuclide or we can say that any of numerous types of the same chemical element with having different masses whose nuclei are unstable and might disintegrate excess amount of energy by a spontaneously emitting radiation in the form of alpha, beta, and gamma rays.
\[^3H\] is known as tritium which contains one number of protons and two numbers of neutrons in its nucleus. And has the mass number = 3. It is the only radioactive isotope of hydrogen, and can decay into helium through the process of beta-decay which might be accompanied by a release of \[18.6{\text{ }}keV\] of energy. The half-life of tritium is something \[12.32\] years. It is a Naturally occurring isotope and is enormously rare on Earth, and the trace amounts are formed by the interaction of the atmosphere with cosmic rays.

Hence, \[^3H\] tritium is the isotope of hydrogen which is Radioactive.

Note: As the Tritium might also be released throughout the testing of nuclear weapons. It has been used in weapons such as in thermonuclear fusion, is a tracer in isotope geochemistry, and also specialized in self-powered lighting devices.
