  • And what we now see is that-- to see whether that could be the case or not, we've got to get clear in our own minds about whether we believe in a neutral container theory, ... a positive, valuable container theory or-- and among those, between a fantastic and a modest container theory.

    现在我们可以看到-,情况是不是这样,我们就要想清楚,我们相信的是中性容器理论,是积极的有价值容器理论还是-,有价值容器理论中的,理想容器理论或保守容器理论。

  • So again, we should be able to check all of our formal charges and make sure they add up to 0, which they do, and that makes sense, because we have a neutral atom in terms of thionyl chloride.

    因此同样地,我们可以检验一下,我们所有的形式电荷是否正确,确保它们加起来等于零,而它们确实是这样,这是合理的,因为亚硫酰氯是一个中性原子。

  • So, by the same logic, that means that all of our positively charged ions are, in fact, going to be smaller in terms of radius, compared to their neutral parents.

    那么,按照相同的逻辑,我们所有的正离子,事实上,它们的半径都会缩小,与它们的中性母体相比。

  • And what's important to keep in mind about formal charge is if we have a neutral atom, such as we did in thionyl chloride here, the sum of the individual formal charges on individual atoms within the molecule have to equal 0.

    而关于形式电荷记住一点是很重要的,那就是如果我们有一个中性原子,比如亚硫酰氯,那么这个分子中的所有原子的,形式电荷之和应该等于零。

  • So, for example, if we think of the fluorine minus case, would you expect fluorine minus to be larger or smaller than neutral fluorine? Okay. I heard mostly larger, but a little bit of a mix in there, and it turns out that larger is correct.

    比如,如果我们来考虑一下负一价的氟离子的话,大家认为它大一些还是小一些?,对比于比中性氟原子,好的,我听到大部分人说大一些,但是也有一些不同意见,而正确答案应该是大一些。

  • In case 2, we're taking the 3 p out of the neutral atom, whereas in case 3, we're taking it out of the ion.

    在第二种情况中,我们要从中性原子中拿走,3,p,电子,而在第三种情况中,我们要从这个离子中拿走它。

  • So that doesn't make a difference for us when we're talking about neutral atoms, 4s because we would fill up the 4 s first, because that's lower in energy until we fill it, and then we just keep going with the d orbitals.

    所以那对我们来说没什么不同,所以当我们讨论中性原子时,因为我们会首先填充,因为在我们填充它之前它的能量都较低,然后我们继续填充d轨道。
