So that means we have four bounce electrons for carbon for h, because we have only one electron, and this one electron is an outermost one s shell, we have one balance electron for each H atom. So four plus three, because we have three h atoms, and each h atom donates one balance electrons, we have a total of seven electrons. Now, notice that this guy is neutral, so this stays the same. If, for example, this had a negative one on top, that means we have one extra electron. So if there would be a negative one here, this would have been eight electrons. But since this is neutral, there's no charge on top.
