7.4: The Bohr Model

  • Page ID
  • As we know it the atom is made up of neutrons, protons, and electrons. While the neutrons (0 charge), and the protons (positive charge) make up the nucleus of the atom, the electron (negative charge) circle around the nucleus much like the orbiting of planets around the sun. According to old theories it was known that electrons are in constant motion around the nucleus while emitting energy. According to this idea as the electrons lost energy they would get closer and closer to the nucleus and eventually crash into it. This problem was solved when Niels Bohr created a model of a hydrogen atom.
