Which element is most abundant in the Sun?

Which element is most abundant in the Sun?

• A. Oxygen
• B. Helium
• C. Hydrogen
• D. Nitrogen

Answer: (C)

Hydrogen is the most abundant element in the Sun. The Sun formed from a giant cloud of gas mainly made of hydrogen and helium, with hydrogen constituting the majority of the mass. In the Sun’s overall composition, hydrogen accounts for roughly three quarters, helium about a quarter, and the remainder consists of heavier elements. Because hydrogen is so plentiful, it dominates the Sun’s makeup. The Sun’s energy comes from hydrogen fusion in its core, converting hydrogen into helium and releasing energy, which is consistent with hydrogen being the most abundant element. Helium is the next most abundant, while oxygen, nitrogen, and other heavier elements appear in much smaller amounts.
