What is the nuclear fuel in the sun? Describe the process by which energy is released in the sun. Write the equation of the nuclear reaction involved.
Hydrogen gas is the nuclear fuel in the sun. The sun can be assumed as a huge thermonuclear furnace where hydrogen atoms continuously get fused into helium atoms. Hence, the mass during these fusion reactions gets lost and as a product energy is being produced.
411H 42He + 2+10e + tremendous amount of energy
