So if we want to write out what that would be, it would just be to say that f minus is isoelectronic with neon.
那么如果我们把它写出来,它应该就是负一价的氟离子与氖原子是等电子的。
So for example, if we think about fluorine, 1 s 2 2 s 2 2 p 5 that has an electron configuration of 1 s 2, 2 s 2, 2 p 5, so all we would need to do is add one more electron to get the same configuration as for neon.
比如,如果我们考虑氟原子的话,它的电子排布是,因此我们所需要做的就是给它加上一个电子,使得它与氖原子的电子排布相同。
- Then also, nitrogen, 3 minus -- these are all going to be isoelectronic with neon.
然后还有,氮,负三价-,这些都是与氖原子等电子的。
So, we can say that -- if we have neon here and we want to think about what's isoelectronic, -- f minus would be isoelectronic. We also have oxygen -- what would the charge on oxygen be? Um-hmm, right. 2 minus.
那么,我们可以说--如果我们这里有氖原子,而我们想知道与它等电子的是什么,负一价的氟离子就是与它等电子的,我们还有氧-,氧应该是几价的?没错,负二价。
In the first case, so here is the electron configuration of neon.
首先,这是氖原子的电子排布。
So let's take the example of neon.
那么就让我们以氖原子为例。
So if that's the case doing a quick little calculation, what would the ionization energy be for a 2 p electron in neon?
么请稍微计算一下,氖原子的,2,p,电子的,电离能是多大?
