Across
  1. 1. the pattern of colored lines, it turned out to be unique for each element
  2. 3. states that no two identical fermions can occupy the same quantum state simultaneously
  3. 7. they are the outermost shell in the atom which are involved in chemical bonding
  4. 8. are dots that represent the valence electrons involve only the outer s and p electrons
  5. 10. a shorthand for writing an element's electron configuration where the symbol of the noble gas that comes immediately before the element is placed in brackets
  6. 11. states that electrons must fill the lowest energy sublevel before any can be placed higher
  7. 13. electrons with the lowest energy state, and can only go up to 7 energy levels.
  8. 16. an atom or group of atoms with a nonzero charge is an ion
  9. 19. is the fundamental property of all submicroscopic systems that cannot be avoided
Down
  1. 1. that have absorbed energy and moved some of their electrons to higher energy levels.
  2. 2. are the distance of an electron from the nucleus corresponding to a particular energy level
  3. 4. identifies the principle or main energy level of an electron
  4. 5. The arrangement of electrons in an atom of an element in its ground state
  5. 6. Negative ion
  6. 9. used to illustrate the electron configuration of an atom
  7. 12. are mass less light particles
  8. 14. it states that electrons are both particles and waves which is a dual nature
  9. 15. states that as electrons fill a sublevel, all orbitals receive one electron with the same spin before electrons begin to pair up
  10. 17. Positive ion
  11. 18. it divides the orbits and tells how many electrons a orbit can have
