Correct Answer - Option 4 : Protium, deuterium and tritium
Concept:
Isotopes of hydrogen is: Protium Deuterium Tritium
There are three known isotope of hydrogen, each possessing an atomic number 1, 2, 3 respectively. These are named as protium, deuterium, and tritium.
Protium:
The most common is the ordinary hydrogen usually called protium. It has one proton in the nucleus and an electron revolving around it.
Protium is a selective “proton pump inhibitor”, a medicine which reduces the amount of acid produced in your stomach. It is used for treating acid- related diseases of the stomach and intestine.
Deuterium:
The second isotope of hydrogen is called heavy hydrogen or deuterium. It consist of one proton and one neutron in the nucleus and electron revolving around it.
Deuterium is not a radioactive and does not represent a significant toxicity hazard. Water enriched in molecules that include deuterium instead of protium is called Heavy water. Deuterium and its compounds are used as a non-radioactive label in chemical experiments and in solvent.
It is widely used in prototype fusion reactors and has their application in military, industrial and scientific fields.
In nuclear fusion reactors, it is used as a tracer and it is responsible to slow down neutrons in heavy water moderated fission reactors.
Tritium:
The third isotope of hydrogen is called tritium. It consist of one proton and two neutrons in the nucleus and an electron revolving around it.
Trace amount of tritium occur naturally because of the interaction of cosmic rays with atmospheric gases. Tritium has also been released during nuclear weapon tests. The most common methods of producing tritium is by bombarding a natural isotope of lithium, lithium-6 with neutrons in a nuclear reactor.
