The Sun is primarily made up of which gas?

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

Answer: (A)

The Sun is made mostly of hydrogen by mass. Hydrogen is the most abundant element in the cosmos, and the Sun’s material is roughly three-quarters hydrogen, with helium making up most of the rest and only a small amount of heavier elements. This hydrogen-rich composition is what powers the Sun: hydrogen nuclei fuse into helium in the interior, releasing the energy that we see as sunlight. Oxygen and nitrogen are present but in much smaller amounts, and helium is the second most abundant element, not the primary one. So, the primary gas is hydrogen.
