  2. 2. The Three Physicists Louie de Broglie Erwin Schrodinger Werner Karl Heisenberg Quantum Mechanical Model
  3. 3. Quantum mechanics • examines the wave motion of objects Atomic orbital • Specified by three quantum numbers
  4. 4. Quantum Numbers According to Heisenberg’s Uncertainty Principle, it is not possible to give the exact position of an electron and its energy at the same time. But the probability of finding an electron in an orbital of given energy can be determined.
  5. 5. The 3 Quantum Numbers Principal Quantum Number, n Azimuthal Quantum Number, l Magnetic Quantum Number, ml
  6. 6. Principal Quantum Number main energy level of an orbital. Indicates the relative size of the orbital an increase in n also means increase in the energy of the electron in the orbital. n= 1, 2, 3….
  7. 7. Azimuthal Quantum Number also called Angular Momentum Number defines the shape of the orbital. values range from 0 to n-1. l = n - 1
  8. 8. Azimuthal Quantum Number l Sublevel Orbital Shape 0 sharp - s spherical 1 principal - p dumbbell- shaped 2 diffused - d cloverleaf 3 fundamental - f too complex
  9. 9. S- orbital • Spherical shape with the nucleus at its center
  10. 10. P-orbital • “dumb-bell shape”
  11. 11. D-orbital • With 5 different orientations
  12. 12. Azimuthal Quantum Number A sublevel in a particular main energy level is defined by its n and its l values. n l Kind of Sublevel 1 0 1s 3 1 3p
  13. 13. Magnetic Quantum Number, ml describes the orientation of the orbital in space. values are –l to +l values per sublevel = 2l +1.
