And because it is much more likely that electron density will be found around the oxygen than around the h atoms, and at any given moment in time, that oxygen atom will have a partial negative charge, and the two h atoms will be deficient of the electron density, and so they will have a partial positive charge. Now, from physics, we know that whenever we have the separation of two opposite charges, whenever a positive charge is separated from a negative charge by a certain distance, there will exist an electric dipole moment as a result of that separation of charge. So what does that mean about this water molecule here? So basically, we have this partial positive charge that is a certain distance, this distance here, away from this partial negative charge. And so from physics, we know there will be an electric dipole moment that will exist and will point in the following general direction. Now.
