The electron is a subatomic particle, symbol eâ or Î²â, with a negative elementary electric charge. Electrons belong to the first generation of the lepton particle family, and are generally thought to be elementary particles because they have no known components or substructure. The electron has a mass that is approximately 1/1836 that of the proton.
Describe: Potential Energy in Atoms. a. the more distant electrons are from the nucleus, the greater their potential energy. b. changes in the potential energy of electrons can occur only in steps of fixed amounts. c. an electron cannot exist between its fixed states of potential energy. Define: Energy Levels.
