It turns out that it's going to be a little bit different when we're talking about positive ions here.

结果是当我们讨论阳离子时,有一些不同。

For example, the positive ions, these are electron deficient.

例如，正离子，是缺少电子的。

But we'll go over that, particularly some exceptions, when we're filling in electron configurations, and how we would go about doing that for positive ions, which follow a little bit of a different procedure.

但是我们将会重温它们，特别是一个特例，当我们填充一个电子构型，而且我们会如何着手,处理阳离子，它遵从一些别的不同的过程。

The positive ions are electron deficient, and these are known as cations.

正离子是缺少电子的，这些就是正离子。

So the correct answer for titanium plus two Ar3d2 is going to be argon 3 d 2, whereas if we did not rearrange our order here 4s2 we might have been tempted to write as 4 s 2 so keep that in mind when you're doing the positive ions of corresponding atoms.

所以正2价钛离子,的正确答案是，然而如果我们不重新安排顺序,我们可能会写出2,所以请记住,它当你们在解关于原子,的正离子的时候。
