What are the chemical make-up elements on the sun?
The Sun primarily consists of hydrogen (about 74% by mass) and helium (about 24% by mass), with trace amounts of heavier elements such as oxygen, carbon, neon, and iron. The high temperatures and pressures in the Sun's core allow nuclear fusion reactions to occur, converting hydrogen into helium and releasing energy in the form of light and heat.
