But, can you see that as you get really close together the negative electronic cloud surrounding the two ions start to sense one another.

然后当你真的让它们,离得很近时,这两个离子周围的负电子云能感应到对方。

And also in a very sort of pragmatic sense, in a negative way, it's tax-deductible.

同时，从实用的角度来讲，或是从一个消极的角度，这种捐款是免税的。

it's an easy calculation -- we're just taking the negative of the binding energy, again that makes sense, because it's this difference in energy here. So what we get is that the binding energy, when it's negative, the ionization energy is 5 . 4 5 times 10 to the negative 19 joules.

这个计算很简单-我们,只需要取结合能的负值,同样这很容易理解，因为这就是这的能量差,所以我们得到的就是结合能,当它取负值，电离能就是5。45乘以。
