And in this case, the tie-breaker goes to the molecule in which the negative charge is on the most electronegative atom.

而在这种情况下，我们需要进行“附加赛“,也就是看看分子中带有负的,形式电荷的原子是不是电负性最高的。

Yup. So it's just that ionization energy 94×10-18J that we have experimentally measured, 3 . 9 4 times 10 to the negative 18 joules.

它就是我们通过实验测得的,电离能3。,我们用所有的这些。

However, if there are repeated, unexcused absences, there will be an adjustment in the grade calculation, and it will be worth twenty to twenty-five percent of your grade, and it will be a negative grade also.

然而，如果有反复的没有理由的缺勤，就会对这个百分比做些调整，出勤率就会占到你分数的百分之二十到二十五，当然也会是负面的评分。

It could be that in thinking about the nature of the combination we're led to see that in certain ways the combination-- the interaction effects--are negative, are bad ones.

可能在考虑这种组合的本质时,我们看到了再某些方面这种组合-,相互影响，是负面的，是不好的。

The only place q1 appears here is here, so when I differentiate again I'm going to get -2b and sure enough that's negative, which is what I wanted to know, just to check that when I'm finding this thing, I'm finding a maximum and not a minimum.

只有这一处有q1,因此二阶导数是-2b,它肯定是个负数了,这正是我们想得到的结果,这就验证了我们刚才得出的,是最大值而不是最小值

The second possible thought that comes to mind for me, in thinking about the negative interaction effects, I call under the title-- I think about under the title-- " "How the Noble Have Fallen."

在考虑负面相互影响时，我想到的第二种可能性，我把它叫做-,我想它叫做-,“贵族如何没落“

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。
