Across
  1. 3. electrons on the outer-most energy level of any atom

  4. 10. a negatively charged ion
  5. 12. a smaller part within a primary energy level
  6. 13. When placing electrons in equal energy orbitals, electrons should not be paired until each equal energy orbital contains one electron
  7. 17. the distance from the atom's nucleus to the outermost energy level
  8. 19. any smaller part of an atom such as a proton, neutron, or electron
  9. 20. a specific amount of energy that can be absorbed by an electron as it moves from ground state to excited state, or released by an electron as it falls from the excited state back to ground state
  10. 21. the amount of energy required to remove one valence electron from an atom
