Best answer
Correct Answer - Option 3 : Tritium

The Correct Answer is Tritium

  • Tritium is the most stable radioactive isotope, with a half-life of 12.32 years.
    • It is a beta-emitting radioactive isotope of hydrogen. 
    • Its nucleus consists of one proton and two neutrons, making it three times as heavy as a hydrogen nucleus (with its one proton) and one-and-a-half times as heavy as deuterium (which contains one proton and only one neutron). 

  • Deuterium
    • It is one of two stable isotopes of hydrogen.
    • The nucleus of a deuterium atom, called a deuteron, contains one proton and one neutron.
    • Deuterium has a natural abundance in Earth's oceans of about one atom in 6420 of hydrogen.
  • Radium
    • It is a chemical element with the symbol Ra and atomic number 88.
    • It is the sixth element in group 2 of the periodic table, also known as the alkaline earth metals. 
  • Protium (isotope) or hydrogen-1
    • It is the most common isotope of the element hydrogen, with one proton, one electron, and no neutrons
