A Phet simulation on Molecule Polarity.

Molecule Polarity Simulation


  • Polarity
  • Electronegativity
  • Bonds
  • Partial Charge
  • Dipole


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.

Sample Learning Goals

  • Predict bond polarity using electronegativity values
  • Indicate polarity with a polar arrow or partial charges
  • Rank bonds in order of polarity
  • Predict molecular polarity using bond polarity and molecular shape
