- Nitrogen
- Hydrogen
- Oxygen
Hint:
Nuclear Fusion begins with protons and through a series of steps, these protons fuse together and are turned into helium.
The correct answer is: Hydrogen
In a nuclear fusion, a fast neutron and a helium atom are created when deuterium and tritium combine. Deuterium (D) and tritium (T) are isotopes of hydrogen.
Hence, Hydrogen atom acts as a reactant in nuclear fusion reaction.
