So the blue sphere basically designates our partially negative oxygen, while these red spheres designate the partially positive h atoms. And so if we have these 123456 water molecules in close proximity, they will orient themselves with respect to one another in such a way to basically maximize the amount of electric interactions. They're actually electromagnetic, but we can say electric interactions between the different atoms on different molecules. So because these h atoms have a partially positive charge, they will be attracted to the partially negative oxygen atoms. And so if we look at these two water molecules, for example, this H atom of this water molecule will try to get as close as possible to this partially negative oxygen atom. And this bond is known as an intermolecular bond.
