说到形式电荷，基本上形式电荷就是，单个原子在形成分子之后，是得到了电子还是失去了电子的一种量度。

那么这就意味着如果我们把这个分子中，所有的形式电荷加起来，我们应该会看到它们加起来，之后得到的净电荷量为负一。
So that means if we add up all of the formal charges within the molecule, what we would expect to see is that they sum up to give a net charge of negative 1.
对于任意净电荷的情况，我们都可以这样做，比如假设我们有一个带两个正电荷的分子，那么所有的形式电荷加起来应该等于正二，等等。
So we can do this for any final charge we have, if we have a molecule that has a charge of plus 2, then all of the formal charges should add up to plus 2 and so on.
