Hydrogen is the most abundant element in the Sun, making up about 74% of its mass. The Sun is a massive ball of gas, primarily composed of hydrogen and helium, which together constitute nearly all of its mass. The nuclear fusion processes in the Sun's core convert hydrogen into helium, releasing energy that powers the Sun and produces the sunlight we see. Helium is the second most abundant element, making up approximately 24% of the Sun's mass, while heavier elements like oxygen and carbon are present in much smaller quantities.
