Chadwick's Neutron

Chadwick's neutron is a subatomic particle discovered by James Chadwick in 1932. It is a neutral (uncharged) particle found in the nucleus of atoms, alongside positively charged protons. Neutrons help stabilize the nucleus by moderating the electromagnetic repulsion between protons. Because they have nearly the same mass as protons, neutrons play a key role in nuclear reactions and processes like nuclear fission. Their discovery explained mysteries about atomic structure and paved the way for advances in nuclear physics and energy.
