Question

Give one word for the following.

A non-metal which is the source of energy in the sun and stars.

Answer 1

• Hydrogen is the non-metal which produces energy in the sun and the stars.
• The sun and the stars are comprised of 75% hydrogen gas. These hydrogen atoms undergo fusion to produce energy.
• In nuclear fusion, the hydrogen atom fuses together to form helium, and as a by-product, a massive amount of energy is released.
• Therefore, hydrogen is the key element to producing energy from stars and the sun.
