Answer: The main components of the Sun are Helium and Hydrogen.

Step-by-step explanation:

Sun is the only star present in Our Solar System around which 8 planets revolve.

Sun is made up of many elements, some of them are: Hydrogen, Helium, Carbon, Nitrogen and Oxygen. The percentages of these elements by mass in Sun are:

Hydrogen: 70%

Helium: 28%

Carbon, Nitrogen and Oxygen: 1.5%

Other elements: 0.5%

In Sun, nuclear fusion reaction takes place where hydrogen undergoes fusion with other hydrogen nuclei to form helium nuclei. Equations for nuclear fusion are given as:


_1^1\textrm{H}+_1^1\textrm{H}\rightarrow _1^2\textrm{H}+_1^0e+\gamma\\\\_1^2\textrm{H}+_1^1\textrm{H}\rightarrow _2^3\textrm{He}-+\gamma\\\\_2^3\textrm{He}+_2^3\textrm{He}\rightarrow _2^4\textrm{He}+2_1^1\textrm{H}\\\\_1^0e+_(-1)^0e\rightarrow \gamma

Hence, the main components of the Sun are Helium and Hydrogen.
