Electron Configuration

005 - Electron Configuration In this video Paul Andersen explains how to write out the electron configuration for atoms on the periodic table. More importantly he shows you why electrons arrange themselves in shells, subshells and orbitals by using Coulomb's law and studying the first ionization energies of different atoms. ANSWERS: Cl - [Ne] 3s^2 3p^5 Ag - [Kr] 4d^10 5s^1 - Did you get [Kr] 5s^2 4d^9? There are a few exceptions to this law. Most of them are found in the f-block metals and they are not of much chemical significance. Music Attribution Title: String Theory Artist: Herman Jolly http://sunsetvalley.bandcamp.com/trac...
