Chem 6A Presentation #5 2007-10-08 1 Overview Chapter 1: The Quantum World What are atomic orbitals ? What's the relationship between quantum numbers and orbital shape/structure? What are the relative energies of electrons in different orbitals? What is electron spin ? What's the exclusion principle ? How is an electron affected by other electrons in an atom? What is an electron configuration , and how do we build one?

2 What's the relationship between quantum numbers and orbital shape/structure? An atomic orbital is specified by 3 quantum numbers: n , , and m . n : energy level or shell ℓ: distinguishes the different sublevels or subshells ℓ = 0: s sublevel ℓ = 1: p sublevel ℓ = 2: d sublevel ℓ = 3: f sublevel m : orientation of orbital in space Each sublevel is designated by combining the value of n with the letter designation, e.g., “2 s ”, “3 d
