Valence Shell Electron Pair Repulsion.
Help predict shape of electron pairs, like bonding and lone pairs, all are negative so they repel eachother.

What is a Dipole Moment?
The electric dipole moment for a pair of opposite charges of magnitude q is defined as the magnitude of the charge times the distance between them and the defined direction is toward the positive charge.

What are polar molecules? Give examples of when molecules are polar.

What is the difference between Intramolecular forces and Intermolecular forces?
The Intermolecular Forces (forces between molecules) are weaker than Intramolecular Forces (The Chemical Bonds within an Individual Molecule).
