  1. Shapes and Orientations of Orbitals

  2. Periodic table arrangement • the quantum theory helps to explain the structure of the periodic table. • n - 1 indicates that the d subshell in period 4 actually starts at 3 (4 - 1 = 3).

  3. The location of electrons is described by: • n, l, ml • n = size, l = shape, ml = orientation

  4. Electron clouds • The “probability” of finding an electron around a nucleus can be calculated. • Relative probability is indicated by a series of dots, indicating the “electron cloud”. • 90% electron probability/cloud for 1s orbital (notice higher probability toward the centre)

  5. p orbitals and d orbitals p orbitals look like a dumbell with 3 orientations: px, py, pz (“p sub z”). Four of the d orbitals resemble two dumbells in a clover shape. The last d orbital resembles a p orbital with a donut wrapped around the middle.
