Discovery of Proton & Neutron

The video tutorial explains the emission of Canon rays, which are positively charged particles known as protons, embedded in the nucleus of an atom. It details the charge and mass of protons and contrasts their properties with electrons in electric and magnetic fields. The discovery of neutrons is discussed, highlighting their neutral charge and presence in the nucleus. The tutorial also covers the properties of subatomic particles, including electrons, protons, and neutrons, with a focus on their charges and masses.
