What two elements compose roughly seventy-three percent and twenty-five percent of the Sun's mass, respectively?
Answer
Hydrogen and Helium
The Sun's elemental composition is overwhelmingly dominated by the two lightest elements in the universe. Specifically, the text details that hydrogen makes up roughly seventy-three percent of the Sun's mass, while helium accounts for approximately twenty-five percent. Together, these two elements constitute ninety-eight percent of the Sun's total mass. The remaining small fraction consists of trace amounts of heavier elements such as oxygen, carbon, neon, and iron. This elemental makeup is the source material that, when subjected to extreme stellar conditions, transforms into plasma.
