好，这就是等电子离子的概念。

So, that's the idea of isoelectronic ions.

镁二正离子，同样也与氖等电子。

Magnesium 2 plus, it is also isoelectronic with neon.

包括原子半径，以及等电子原子的概念。

This includes atomic radius and the idea of isoelectronic atoms.

And then, if we have time at the end, we'll introduce one last topic, which is isoelectronic atoms and ions.

最后，如果有时间的话，我们将再介绍最后一个主题：,等电子原子与离子。

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。
