And so now we have net charge.

然后我们得到了净电荷。

youdao

Each atom would have a very small net charge.

每一个原子都会有一个很小的净电荷。

youdao

Atoms have equal Numbers of protons and electrons, so have no net charge.

由于原子内的质子数与电子数相同，所以原子不带电荷。

youdao

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。

So, if we think about the second case here where we have c n minus, now we're talking about a molecule with a net charge of negative 1.

那么，如果我们考虑的是第二个例子,也就是氰离子，那么现在我们讨论的是一个净电荷量为负一的分子。

Now the last thing is that because the neutron has no net charge, we can change neutron number.

现在，最后一件事是,因为中子没有净电子，我们可以改变中子数。

Tight credit controls--net charge-offs are only 4.7% of the portfolio--helped AmeriCredit survive the 1997 meltdown of the subprime lending industry.

FORBES: U-Turn

However, the annualized net charge-off rate for US credit cards rose marginally from 7.26% in October to 7.56% in November.

Even through the recession, CDFI portfolios performed as well as or better than mainstream financial institutions, with CDFI annual net charge-offs lower in both 2008 and 2009 than FDIC-insured institutions.
