  2. the distance between two consecutive wave peaks is the ______________
    wavelength (lambda)
  3. the __________ indicates how many wave peaks pass a certain point per given time period.
    frequency (nu, "v")
  4. a beam of light traveling through space is a stream of tiny packets of energy called _____________
  5. only certain values are allowed (i.e. all hydrogen atoms have the same set of discrete energy levels). They are _______
  6. the ____________ model of the atom describes how the electron's position is represented (not a circular orbit)
    wave mechanical
  7. a representation of the space occupied by an electron in an atom (the probability distribution for the electron) is known as a(n) __________
  8. Red wavelength photons are ________________ while blue wavelengths are ______.

  10. 1S orbital is the ______________ energy state, the "ground state"
  11. ______________ levels, (represented by n=1, n=2 etc) hold each layer of orbitals (1s, 2s 2p, 3s 3p 3d� etc) within each (n) "electron apartments"
    principle energy levels
  12. principle energy levels are divided into __________, which increase with (n) (such as s, p, d, f)
  13. S sublevel holds ___ electrons max
