And so in theory after just 2 or 3 steps you were in order of magnitude farther along in this counting process than I would be because I'd still be on person literally 3 or 4.
因此从理论上说,经过这样短短的两三个步骤,你们就有了分级次序，比我数数快多了,因为我才数到第三四个人。

So what I want to point out is 3d2 what we said now is that the 3 d 2 is actually lower in energy, so if we were to rewrite this in terms of what the actual energy order is, 3d2 4s2 we should instead write it 3 d 2, 4 s 2.
所以我们想指出的是,我们现在所说的是,实际上能量比较低，所以如果我们重新的,写出实际的能量顺序，我们应该写出。

Because if it was a disease that was carried by both humans and squirrels, for example, then in order to get rid of it on the planet, you'd have to vaccinate not only all the people but all the squirrels, right?

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。
