Question

Nuclear fusion reaction that powers the sun involves:

Options

• Uranium splitting into barium and krypton

• Two hydrogen isotopes fusing to form helium

• Carbon fusing with oxygen

• Neutron absorption by plutonium

Answer 1

Two hydrogen isotopes fusing to form helium

Explanation:

\[_1^2\mathrm{H}+_1^3\mathrm{H}\to_2^4\mathrm{He}+_0^1n+17.6\mathrm{~MeV}.\]

Fusion releases more energy per nucleon than fission.
