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 is a huge, glowing sphere of hot gas. Most of this gas is hydrogen(about 70%) and helium (about 28%). Carbon, nitrogen and oxygen make up 1.5% and the other 0.5% is made up of small amounts of many other elements such as neon, iron, silicon, magnesium and sulfur.
Detailed explanation-3: -The Sun is primary hydrogen (75 percent). Hydrogen is the same flammable gas once used to fill airships such as the Hindenburg and are now used in rocket fuel). The rest of the Sun’s makeup is helium (25 percent). Helium is the safer gas we now use to fill airships and party balloons.
