Remember, balanced electrons are those electrons found in the outermost energy shell. For oxygen, that happens to be the N equals two shell. So two plus five equals seven. So seven balance electrons for o, and we have one electron in the balanced electron of one s for H. So we have all together eight electrons, eight balanced electrons that we will have to place around our atoms. So let's begin by placing our oxygen and H adjacent to one another. So we have eight electrons.
