So for example, that might have a formal charge of negative 1, because to some extent it has gained that much electron density that it now has a formal charge that's negative.
比如，可能它的形式电荷为负一，因为在一定程度上它得到了这么多的共用电子密度,那么它现在就有了负的形式电荷。
-
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.
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。

That means that it's harder to make a market for it, so the dealer wants to charge more.
这意味着,这样的品种市场很小,所以中间商要收取更多的费用

He is, after all, on trial for his life, for the charge of impiety.
他可是在接受生死攸关的审判，罪名是亵渎神明。
-
Because it's a gel electricity is going to move through the gel because there are ions in it the same way - for the same reason you don't drop an electrical device into the bathtub because charge moves through water that has ions in it.
由于凝胶中存在离子,电流会通过凝胶,同样--,因为同样的原因你不会把电器扔进浴缸里,因为水里也有离子,所以水可以导电

ve something like, recent study shows of 30,000 Canadians have gone for other countries for health treatments, even though they got it free of charge in Canada, ve get to pay for it somewhere else, and they go.
有大约，You’,最近调查显示是3万加拿大人,去别的国家,寻求医疗，即使在加拿大有免费的，他们在别处得付费，and，they’,他们还是选择出去。
-
So in our first structure, we would find for the nitrogen we have a formal charge 5 minus 4 minus 2, because we're starting with 5 valence electrons, so that is a formal charge of minus 1.
那么在我们的第一个结构中，我们发现氮的形式电荷量是五减去四4,再减去二，因为我们开始有五个价电子，因此它的形式电荷量是负一。

Homes just stay where they are, so we have far fewer accidents, so they don't have to charge as high a premium for the insurance.
而住宅则是固定的,所以发生事故的情况也更少,这就导致保险公司对住房保险收取的保费,不会太高
-
And what you find out if you do these calculations, is that you have a negative 1 for your formal charge on nitrogen, you have a negative 2 for your formal charge on carbon, and you have a positive 2 for your formal charge on sulfur.
而如果你做了这些计算会发现，氮的形式电荷量为负一，碳的形式电荷量为负二，而硫的形式电荷量为正二。
-
First we need to select for actual charge.
首先我们需要根据正确的电荷进行筛选。
-
Charge neutrality won't allow for it.
电中性原则不允许这样。
-
The dealer will charge a higher price for you to buy the furniture than will give to you to purchase the furniture from you; that's how the dealer makes a difference.
中间商给你的报价,会比向你收购同样家具的开价高,这就是中间商如何赚取差价

Most companies do splits because that might close the-- you might have been thinking about investing in Google but you could still--you could just say, I want to buy ten shares or five shares and the broker will do it for you, but they might charge a higher commission.
大部分公司会分割,因为这样会关闭...,比如你想投资谷歌,但是你可以说,我想买十股,或者五股,经纪人会照办,但是会索取更高的佣金
