Nuclear Fusion

Nuclear fusion is a process in which two atomic nuclei combine to form a heavier nucleus. This process releases a large amount of energy and is the fundamental process that powers the sun and other stars. The most common example of nuclear fusion on Earth is the fusion of hydrogen isotopes to form helium, which occurs in hydrogen bombs and experimental fusion reactors.

Key Concepts

• Atomic Nuclei: The central part of an atom, composed of protons and neutrons.
• Energy Release: Nuclear fusion releases a large amount of energy due to the conversion of mass into energy, as described by Einstein's famous equation E=mc^2.
• Stellar Fusion: Nuclear fusion is the primary energy source for stars, including our sun.
• Fusion Reactors: Scientists are working on developing practical fusion reactors as a potentially limitless and clean source of energy for humanity.
