The Modern View of Atomic Structure Physicists have identified a long list of particles which make up the atomic nucleus. Chemists, however, are primarily concerned with the following sub-atomic particles: electron proton neutron Electron The electron is negatively charged, with a charge of -1.602 x 10 -19 Coulombs (C). For convenience, the charge of atomic and sub-atomic particles are usually described as a multiple of this value (also known as the electronic charge ). Thus, the charge of the electron is usually simply refered to as -1 . Proton The proton has a charge of +1 electron charge (or, +1.602 x 10 -19 C ) Neutrons Neutrons have no charge, they are electrically neutral . Note: Because atoms have an equal number of electrons and protons, they have no net electrical charge Protons and neutrons are located in the nucleus (center) of the atom. The nucleus is small compared to the overall size of the atom. The majority of the space of an atom is the space in which the electrons move around. Electrons are attracted to the protons in the nucleus by the force of attraction between
