-- Quantum Numbers Adapted from: David M. Hanson, Foundations of Chemistry, ed, Pacific Crest, 2006. Quantum numbers describe what we refer to as atomic orbitals. While an atomic orbital is a mathematical function describing an electron, chemists often think of anatomic orbim region of space in which an electron can be found. Classic pictures of atomic orbitals describe regions where an electron has a 90 % probability of being within the described surface. Quantum numbers are often described as electron...
