Detailed explanation-1: -The sun is mostly composed of the elements hydrogen (H) and helium (He). By mass the composition of the sun is 92.1% hydrogen and 7.9% helium.
Detailed explanation-2: -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-3: -The Sun is a huge ball of hydrogen and helium held together by its own gravity. The Sun has several regions. The interior regions include the core, the radiative zone, and the convection zone.
Detailed explanation-4: -In the core of the Sun hydrogen is being converted into helium. This is called nuclear fusion. It takes four hydrogen atoms to fuse into each helium atom.
