MCQ The three quarters of Sun is made up ofa)Methaneb)Magnesiumc)Hydro...
Sun is a star. And stars are the source of energy of universe.
They burn their fuel to emit energy.
The fuel is Hydrogen.
Hydrogen after burning (fusion) converts to Helium.
If one day hydrogen is depleted then sun will die. And we know Sun is said to be in young stage. So it must have lots of Hydrogen and less of Helium.
And regarding other elements present there is; during fusion there is a very very small chance of producing other elements. And that sometimes happens, produncing other atom/molecules there.

MCQ The three quarters of Sun is made up ofa)Methaneb)Magnesiumc)Hydro...
The Composition of the Sun
The Sun is mostly made up of hydrogen gas, which accounts for about 74% of its mass. The remaining 25% is mostly helium, with trace amounts of other elements such as oxygen, carbon, neon, and iron. Therefore, the correct answer is option 'C', which is hydrogen.
Importance of Hydrogen in the Sun
Hydrogen is the most abundant element in the universe, and it plays a crucial role in the Sun's energy production through the process of nuclear fusion. In the Sun's core, hydrogen atoms are squeezed together under immense pressure and temperature, causing them to collide and fuse into helium atoms. This process releases a tremendous amount of energy in the form of light and heat, which is what makes the Sun shine.
Conclusion
In conclusion, the Sun is mostly made up of hydrogen gas, which accounts for about 74% of its mass. The remaining 25% is mostly helium, with trace amounts of other elements such as oxygen, carbon, neon, and iron.
