  1. List the noble gases.
  2. Write out the electron configuration for Ar.
  3. Complete the following table:
  4. Complete the following tabletable:
  5. Write out the electron configuration (the l-o-n-g way) for N, Br, Kr, Y.
  6. Write out the electron configuration (the short way) for P, Mn, I, Ba, Tb.
  7. The outermost electrons in an atom are known as "valence electrons."  Which two sets of orbitals (s, p, d, f) are always the outermost occupied ones in any atom?
  8. How many valence electrons are there in each of the atoms you examined in #5 and 6?
  9. What is the most number of valence electrons any atom can have?
  10. List the following orbitals from lowest to highest energy:  2p  2s  4p  3d  1s  3s  5p  4f
  11. List the following orbitals by increasing distance from the nucleus:  2p  2s  4p  3d  1s  3s  5p  4f
  12. Go back and study the other worksheet too - all that wavelength and frequency stuff is important!
