The isotopes of hydrogen are:(A) Tritium and Protium only(B) Deuterium and tritium only(C) Protium and deuterium only(D) Protium, deuterium and tritium
The correct answer is (D) Protium, deuterium, and tritium.
Hydrogen has three stable isotopes:
Protium (symbol: ^1H) - This is the most common isotope of hydrogen and consists of a single proton and no neutrons.
Deuterium (symbol: ^2H or D) - Deuterium has one proton and one neutron in its nucleus.
Tritium (symbol: ^3H or T) - Tritium has one proton and two neutrons in its nucleus.
So, all three of these isotopes exist naturally.
