Hi, I have a quick question. Ignoring quantum stuff, shouldn't I be able to predict the angle between the two hydrogens in a water molecule if I model the three atoms as point charges and assume that both hydrogens have a partial charge of +D and that the oxygen has a partial charge of -2D, and that both the hydrogens are the same distance L away from the oxygen molecule? If I assume these things then assume that the net force on each point charge is 0, shouldn't I be able to get the angle as a function of D and L?
Or is this way hopeless for predicting the angle?
