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。

So, selenium 2 minus is what's going to be isoelectronic, because if you add two electrons to selenium, you'll get the same electron configuration that you have for krypton here.

负二价的硒离子将是等电子的，因为如果你给硒原子加上两个电子，你会得到,和氪原子相同的电子排布。

These are all isoelectronic, they all have the same electron configuration. And we can also think about going back to atomic size for a second.

这些都是等电子的，它们都有相同的电子排布，而,我们还可以再回想一下原子尺寸的概念。

- The answer to that is definitely no -- if they had the same electron configuration, they would, in fact be neon. But we can think about different ions that have this electron configuration.

答案是绝对没有-,如果它们具有相同的电子排布，那么它们，实际上,将都是氖，但是我们可以想一想,有没有其它离子具有这种电子排布呢？

So we can go ahead and think about, well, are there any other atoms that are going to have the same electron configuration?

那么我们可以开始想一想，好，有没有其它原子,具有相同的电子排布？

Let's move on to the last topic in terms of this first exam, which is thinking about the idea of isoelectronic atoms, or isoelectronic ions. And isoelectronic is very straightforward, it just means having the same electron configuration.

下面我们继续讲第一次考试的最后一个主题，也就是等电子原子，或等电子离子的概念，“等电子的“是非常直接的表达，它的意思就是具有相同电子排布的。
