Document Summary

Electron configuration is a shorthand notation that shows electron arrangement within orbitals. Electron configuration can be written in one of 3 methods: energy-level diagrams, complete electron configuration, condensed electron configuration (aka noble gas configuration) It"s easier to sleep downstairs on the couch than to climb the stairs to your bedroom. If your friend is already sleeping on the couch, then you will go upstairs. Pauli"s exclusion principle: no two electron"s have the same 4 quantum numbers, one electron will spin up, the other will spin down.
