What exactly is a dipole moment?

It happens when there is unequal charge density or separation of positive and negative charge. You can use it to measure polarity of a molecule

It is pretty much the polarity between atoms, indicated with an arrow pointing toward the negative delta direction.

Dipole Moment refers to the momentary positive or negative charge which exists on an atom when the electrons are temporarily located at a given position on it. It is represented by an arrow placed between the partial positive and partial negative charges on two atoms, with the arrow pointing toward the partial negative side.

By random chance, the electrons can be concentrated on one side than the other side. If this happens, then the atom will become slightly positive on one side and slightly negative on one side, creating a dipole.

Why do we need to know about the positive and negative charge of the atoms in a molecule using dipole moment? Does this help with Lewis Structures?
