  1. 6. a visual method to show how electrons are distributed within an atom's orbitals, using boxes for orbitals and arrows for electrons to represent their spin and energy level.
  2. 7. Atom or group of atoms with a negative charge.
  3. 10. A shorthand method of representing atoms and valence electrons.
  4. 12. The rule stating electrons fill a sublevel by 1 electron occupying each orbital before a 2nd electron can occupy any orbital.
  5. 13. A measure of the angular moment of an electron in an orbital.
  6. 15. A charged atom or group of atoms due to gain or loss of electrons.
  7. 16. A shorthand method for writing an atom's electron configuration by using the symbol of the noble gas from the previous period to represent the inner-shell electrons.
  8. 17. Any energy state other than the ground state.
  9. 18. Electrons in the outermost energy level of an atom
  10. 19. Divisions of principle energy levels within an atom that are further divided into orbitals.
Down
  1. 1. A massless particle of light consisting of a bundle of wave energy.
  2. 2. A 3D region representing the most probable position of an electron according for an electron according to the quantum mechanical model.
  3. 3. Model proposed by Neil Bhor where electrons move around nucleus.
  4. 4. The current description of both light and matter as having characteristics of waves and particles simultaneously.
  5. 5. The arrangement of electrons in the ground state of the element.
  6. 8. The orbits or energy levels in the atomic models.
  7. 9. Atom or group of atoms with a positive charge.
  8. 10. An incomplete spectrum in the form of a series of colored lines.
  9. 11. The lowest energy level of an electron in the Bohr model.
  10. 14. A principle that states electrons will fill the inner most energy level before the outer most layers.
