.. And so we are not talking about anything that... Processing our tax returns, unfortunately And it's a one-time check.

所以我们讲的并不是。,不巧正在处理退税事宜,而且这个是一次性支票。

And the last thing we do for any of our structures to check them and figure out are these valid or not valid, are these good Lewis structures is to check the formal charge.

而为了检验任何一个结构是否有效,看它们是不是好的路易斯结构,我们要做的最后一件事就是检查形式电荷。

"And,we come and check it out. And,all of our dogs are extremely ball driven they love to play.

This is our little sanity check, the base case.

这是合法性检查，是基本条件。

So again, we should be able to check all of our formal charges and make sure they add up to 0, which they do, and that makes sense, because we have a neutral atom in terms of thionyl chloride.

因此同样地，我们可以检验一下,我们所有的形式电荷是否正确,确保它们加起来等于零，而它们确实是这样，这是合理的，因为亚硫酰氯是一个中性原子。

Well, the reason, the way that we can check it is just to see if it's in between our two extreme 1 cases. We know that it has to be more than 1, because even if we had total shielding, 1 we would at least feel is the effective of 1.

好的我们可以检查它的原因和方式是观察,它是否在我们的两种极端案例之间,我们知道它必须大于，因为即使如果我们有完全的屏蔽，我们最小感到的有效值是。

So again, when we check these, what we want to see is that our z effective falls in between the two extreme cases that we could envision for shielding.

所以当我们再一次检查这些时，我们想看到的是,有效电荷量处于两种极端案例中,这两种极端案例。
