WebJan 30, 2024 · Bohr Diagrams. Bohr diagrams show electrons orbiting the nucleus of an atom somewhat like planets orbit around the sun. In the Bohr model, electrons are pictured as traveling in circles at different shells, depending on which element you have. Figure 2 contrast the Bohr diagrams for lithium, fluorine and aluminum atoms. WebLikewise, if something starts out with a certain net charge, say +100 e, it will always have +100 e unless it is allowed to interact with something external to it. Charge can be created and destroyed, but only in positive-negative pairs. Table of elementary particle masses and charges: Electrostatic charging
