The equation ; 4\ ^ 1 _ 1 H arrow ^ 4 _ 2 He^ 2+ + 2\ e^- + 26\ MeV...

The equation ;

4\ {}^{1}_{1}\text{H} \rightarrow {}^{4}_{2}\text{He}^{2+} + 2\ e^- + 26\ \text{MeV}

represents

Options

A $\beta$ - decay
B $\gamma$ -decay
Cfusion
Dfission

Correct answer

C. fusion

Step-by-step solution

The given nuclear reaction involves the combination of four lighter hydrogen nuclei (

{}^{1}_{1}\text{H}

) to form a heavier helium nucleus (

{}^{4}_{2}\text{He}

).

The process in which lighter nuclei combine to form a heavier nucleus with the release of a large amount of energy is known as nuclear fusion.

Thus, the given equation represents nuclear fusion.
