i dont know but i want to know about it..please..;(
Hydrogen (approximately 74%) and helium (approximately 24%) make up around 98% of the sun's composition. These elements are constantly undergoing nuclear fusion reactions in the sun's core, creating energy and enabling the sun to emit light and heat.
The sun's composition is dominated by two primary chemical elements, which together account for more than 98 percent of its mass. Hydrogen, the lightest and most abundant element in the universe, makes up approximately 74 percent of the sun's mass. Helium, the second lightest element, comprises about 24 percent of the sun's mass, bringing the total to 98 percent. The remaining 2 percent consists of various heavier elements, including oxygen, carbon, nitrogen, and iron, among others.
A substance is called a compound when it is made up of two or more different elements chemically bonded together. Compounds have a fixed chemical composition and properties that are different from the elements that make them up.
