Detailed explanation-1: -About three quarters of the sun is hydrogen, which is constantly fusing together and creating helium by a process called nuclear fusion. Helium makes up almost the entire remaining quarter.
Detailed explanation-2: -The Sun, like others stars, is a ball of gas. In terms of the number of atoms, it is made of 91.0% hydrogen and 8.9% helium. By mass, the Sun is about 70.6% hydrogen and 27.4% helium. The Sun’s enormous mass is held together by gravitational attraction, producing immense pressure and temperature at its core.
Detailed explanation-3: -Introduction: Fusion is the process that powers the sun and the stars. In one example of this type of reaction, two atoms of hydrogen combine together to form an atom of helium. In the process, some of the mass of the hydrogen is converted into energy.
