Chem 1035 Chapter 8 1 of 35Chapter 8Electron Configuration and Chemical PeriodicityUsing the four quantum numbers, we want to distribute an atom’s electrons among the atomic orbitals. The location of an atom’s electrons determine its behavior.Electron Configurationstells where an atom's electrons are (what atomic orbitals)helps us predict chemical reactivity of elements and structures of compounds

Chem 1035 Chapter 8 5 of 35The Periodic Table gives the order in which orbitals are filled: rather than memorizing the energy diagram, you can let the periodic table tell you what orbitals to put the electrons in.nfor sand pelectrons = period numbernfor delectrons = period number - 1nfor felectrons = period number - 2
Chem 1035 Chapter 8 6 of 35Electron Configurations and Orbital DiagramsElectron configuration is indicated by a shorthand notation:Orbital diagrams make use of a box, circle, or line for each orbital in the energy level. An arrow is used to represent an electron andits spin.H───
