So, let's try another example here, and let's try a case now where instead of dealing with a neutral molecule we have an ion, so we have c n minus.
那么,让我们来试一下另外一个例子,这次不是一个中性原子,而是一个离子,氰离子。
So if we add them all up, there should be no net charge on the molecule, if the molecule is neutral.
因此如果我们把它们都加起来,这个分子上应该没有净电荷,如果这个分子是中性的话。
The molecule is net neutral, but this right end is a little bit more negative and the left end is a little bit more positive.
这分子是电中性的,但右边要带一点负电荷,而左边要带一点正电荷。
