Chapter 8: Atoms and the Atomic Theory Multi-electron atoms Electronic Configuration Electron Configuration and the Periodic Table 6 Chemistry 110 Chapter 8 Part 3e Quantum II H atom: each shell (same n ) is Degenerate. Li atom: shells are not degenerate. Helium, Lithium etc. Have very different Properties from 2 or 3 H atoms stuck together.

Chapter 8: Atoms and the Atomic Theory Multi-electron atoms Electronic Configuration Electron Configuration and the Periodic Table electrons like to get as far away as possible from each other. 7 Chemistry 110 Chapter 8 Part 3e Quantum II H e - He e - e - One attraction Two attraction One repulsion Exact solution ( Z =1) Give spdf orbitals Cannot be solved ( Z =2) The greater Z the more difficult the problem. all multi-electron atoms and all molecules are solved (very well) approximately.
