Can someone please define what a dipole moment is?

A dipole moment is the measure of polar covalence of a bond in molecule.

So when an atom is not bonded to itself, does that always result in a dipole moment?

In a bond between two different atoms, there would be a dipole moment. But in a whole molecule, such as CH4, the dipole moments cancel out and the molecule itself is nonpolar.

A dipole moment is a vector measurement of the separation of two opposite electrical charges, calculated by the charge multiplied by the distance between the charges. It comes from a difference in electronegativity between 2 ions and measures the polarity of a molecule.
