Founded in 2002 by Nobel Laureate Carl Wieman, the PhET Interactive Simulations project at the University of Colorado Boulder creates free interactive math and science simulations. PhET sims are based on extensive education <a {{0}}>research</a> and engage students through an intuitive, game-like environment where students learn through exploration and discovery.

Molecule Polarity - PhET Interactive Simulations
The VSEPR model can be used to predict the geometry of molecules and polyatomic ions. Molecular geometry de-scribes the positions of the nuclei in relation to each other. Included in the description are the bond angles, the angles made by the lines join-ing the nuclei of bonded atoms.
2 Αυγ 2012 · Molecular Geometry and Polarity1 Objectives At the end of this activity you should be able to: o Write Lewis structures for molecules. o Classify bonds as nonpolar covalent, polar covalent, or ionic based on electronegativity differ-ences. o Recognize exceptions to the octet rule; draw accurate representations.

The localized electron bonding model describes and predicts the molecular geometry using Lewis diagrams and the VSEPR model. There are four types of crystal lattice structures: ionic, molecular, covalent (network solids), and metallic.
When is a molecule polar? Change the electronegativity of atoms in a molecule to see how it affects polarity. See how the molecule behaves in an electric field. Change the bond angle to see how shape affects polarity. See how it works for real molecules in 3D. Sample Learning Goals predict bond polarity using electronegativity values
