Chadwick experiment

Chadwick's experiment involved bombarding beryllium atoms with high-energy alpha particles, causing the emission of a new type of neutral radiation. This radiation was later identified as neutrons, particles without electric charge. The discovery explained how atomic nuclei could hold together despite repulsive forces between positively charged protons, advancing our understanding of atomic structure. Essentially, Chadwick revealed that neutrons are a fundamental component of the atom's nucleus, helping explain nuclear stability and paving the way for nuclear physics developments.
