What are the different layers of the Suns atmosphere?
The Sun’s Atmosphere The atmosphere of the Sun and most of its interior are made mostly of hydrogen and helium. In the atmosphere, helium constitutes 73% of the mass while helium constitutes 25%, leaving only 2% for other elements. For the Sun as a whole (both atmosphere and interior), hydrogen averages at 70.5%, helium at 27.5%, and all other elements at 2%. The Sun is completely in a gaseous phase. The gas, made of the elements mentioned above, is either neutral or ionized depending on the atmospheric parameters at different locations. In an ionized gas, also called ‘plasma,’ some or all electrons orbiting the nuclei are stripped from the atoms, due either to violent collisions with other atoms or the absorption of light of sufficient energy. The higher the temperature of the gas the more favorable the conditions for the formation of a plasma.
