Nucleon

A nucleon is a fundamental particle found in the nucleus of an atom, specifically referring to protons and neutrons. Protons carry a positive charge, while neutrons have no charge. Together, these particles determine the atomic mass and play a crucial role in the stability of the nucleus. The number of protons in an atom defines its element, while neutrons can vary, giving rise to different isotopes of the same element. Nucleons are held together by the strong nuclear force, which is one of the four fundamental forces in nature, ensuring the nucleus remains intact.
