WebJul 30, 2024 · Atoms themselves are composed of subatomic particles. The electron is a tiny subatomic particle with a negative charge. The proton has a positive charge and, while small, is much larger than the electron. The neutron is also much larger than an electron but has no electrical charge. WebAtoms are made up of the same amount of negative and positive charges. In Thomson’s model, atoms were described as a spherical cloud of positive charges with embedded …
