Question

Which of the following statement is correct regarding the nuclear fusion reaction inside the sun?

• A. Four nuclei of hydrogen combine to form two nuclei of helium
• B. Four nuclei of hydrogen combine to form four nuclei of helium
• C. Four nuclei of hydrogen combine to form one nucleus of helium
• D. Four nuclei of hydrogen combine to form three nuclei of helium

Answer 1

The correct option is C Four nuclei of hydrogen combine to form one nucleus of helium

The nuclear fusion inside the sun is given by,

$4_1{\text{H}}^1\to {}_2{\text{He}}^4+2_{+1}{e}^0+Q\left(26.7\text{MeV}\right)$

So, $4$ hydrogen nuclei combine to form one nucleus of helium.

Hence, option $\left(C\right)$ is correct.
