  • Bohr Model
    A representation where electrons move in fixed circular paths around a nucleus, each path corresponding to a specific energy level.
  • Electron
    A negatively charged subatomic particle found in shells around the nucleus, responsible for chemical behavior.
  • Nucleus
    The dense central region of an atom containing protons and neutrons, around which electrons orbit.
  • Shell
    A circular path or energy level where electrons are grouped based on their distance from the nucleus.
  • n
    A variable representing the number of a shell or energy level, with higher values indicating shells farther from the nucleus.
  • Potential Energy
    The stored energy an electron has due to its position within a specific shell relative to the nucleus.
  • Proton
    A positively charged subatomic particle located in the nucleus, contributing to atomic identity.
  • Neutron
    An electrically neutral subatomic particle found in the nucleus, adding to atomic mass but not charge.
  • Absorption
    A process where an electron gains energy from an external source, allowing it to move to a higher shell.
  • Emission
    A process where an electron releases energy and returns to a lower shell, often emitting a photon.
  • Excited State
    A condition where an electron occupies a higher shell after absorbing energy, above its lowest possible energy.
  • Ground State
    The lowest energy configuration of an electron, where it resides in the closest possible shell to the nucleus.
  • Energy Transition
    A change in an electron's energy level as it moves between shells, requiring or releasing specific energy amounts.
  • Photon
    A packet of energy that can be absorbed or emitted by an electron during transitions between shells.
  • Energy Level
    A quantized state associated with a shell, determining the potential energy of electrons within it.
