Periodicity

• Sub-shells are an orbital or combination of orbitals.

  • The s orbital = 1-5
  • The p orbital = 2-5
  • The d orbital = 3-5
  • The f orbital = 4-5
• Order of orbitals:

  1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d, 7p

  (Don't really need to know the f orbital, questions of electron configuration do not go that far.)
• Orbitals on a Periodic Table:

  A) S

  B) D

  C) P

  D) F
