Valence Shell Electron Pair Repulsion fundamentally states that because all electrons are negative, groups of them around central atoms will repel to get the maximum amount of space possible.  This ends up making some really spectacular 3-D shapes!  This downloadable table includes molecular and domain geometries as well as bond angles.  The corresponding hybridizations are also included for those that need them.  All the information you need for a chemistry course (even college!) or AP chemistry exam prep is here, so feel free to download and share if you find it useful.  Determining the number and configuration of electron groups requires using a periodic table to do a Lewis Dot Structure first.  You can download one here:
