So Enrico Fermi called Pauliâs particle the neutrino, Italian for âlittle neutral one.â) 7. Subatomic particles are actually waves (sometimes) Thomson won a Nobel Prize in 1906 for the experiments establishing the existence of the first known subatomic particle, the electron. So he must have been surprised when, in 1937, his son George also won a Nobel Prize â for demonstrating that electrons (at least in some experiments) were actually waves.
Sub-Atomic Particles. A typical atom consists of three subatomic particles: protons, neutrons, and electrons (as seen in the helium atom below). Other particles exist as well, such as alpha and beta particles (which are discussed below). The Bohr model shows the three basic subatomic particles in a simple manner. Most of an atom's mass is in the nucleusâa small, dense area at the center of every atom, composed of nucleons. Nucleons include protons and neutrons. All the positive charge of an atom is contained in the nucleus, and originates from the protons. Neutrons are neutrally-charged. Electrons, which are negatively-charged, are located outside of the nucleus. Introduction The Bohr model is outdated, but it depicts the three basic subatomic particles in a comprehensible way.
