Now, another way of representing this unequal distribution is by using this arrow. So we draw an arrow towards where our electrons are being pulled and our electrons are being pulled towards the larger nucleus. So towards the f.
And we draw kind of a plus sign on the end where there's a partial positive charge. So the same thing goes for h and o, we're going to have an arrow this way and we're going to have an arrow this way. Now, another way of looking at this is via electronegativity. The atom that has a larger electronegativity, it will pull or attract electrons more strongly.
