Which statements are true of the reactions in the Sun?

Check all that apply.

A. The reactions occur because the nuclei are moving very slowly.
B. They are fission reactions.
C. Helium atoms are produced.
D. They occur between hydrogen atoms.

The reactions occur between fast moving hydrogen nuclei. When two hydrogen nuclei combine together, chain of reactions occur and finally forms helium nuclei.

The reaction which hydrogen atoms undergo is Nuclear fusion reactions. These reactions are defied as the reactions in which smaller nuclei combine together to form a single heavier nuclei.

The reactions that occur follows the series of equation:

[tex]_1^1\textrm{H}+_1^1\textrm{H}\rightarrow _1^2\textrm{H}+_{+1}^0\textrm{e}+\text{energy}\\\\_1^2\textrm{H}+_1^1\textrm{H}\rightarrow _2^3\textrm{He}+\text{energy}\\\\_2^3\textrm{He}+_1^1\textrm{H}\rightarrow _2^4\textrm{He}+_{+1}^0\textrm{e}+\text{energy}[/tex]

The overall equation for the above reactions is:

[tex]4_1^1\textrm{H}\rightarrow _2^4\textrm{He}+2_{+1}^0\textrm{e}+\text{energy}[/tex]

Hence, the correct statements are Option C and D.
