-
Because it was in the 1950's or so, maybe the late 1940's, that people started to discover lithium, even though it had no natural function, it did do something in our bodies.
因为在二十世纪五十年代左右，可能是四十年代末期，人们开始发现锂，尽管不参与人体的正常生理活动，但是它确实会对我们的身体产生影响。
-
We can do the exact same thing when we talk about lithium, but now instead of breaking it up into two wave functions, we're breaking it up into three wave functions because we have three electrons.
在讨论锂时,我们也可以做，完全相同的事情,但不是把它分为两个波函数，而是分为三个波函数,因为我们有3个电子。

s1 Here is 1s atomic. But lithium has 2s1, so I need a 2s atomic orbital here and likewise over here.

Here's a, actually here it did take 25 years, but they did, they did eventually step on before we started drinking 7-Up.

And the other thing to point out, which I don't know if this is true or not, but does anyone know -- well that's part's true, does anyone know what the atomic mass of lithium is?
另外需要指出的一点是，关于这点我不知道是不是真的，有人知道--这部分是真的，有人知道锂的原子量吗？

-
This one is calculable by the Bohr model because lithium 2plus is a one electron system.
这个可以通过波尔模型计算而得到,因为锂2+是单电子系统。

And this is just a picture showing some of these sizes with their parent. So, for example, a lithium here, you can see how lithium plus is smaller than the actual lithium atom in its neutral state.
这是一张对比图,展示某些离子与它们的母体，比如，这里是锂，大家可以看到正一价锂离子是多么的小,与中性锂原子相比。

Lithium has three electrons. If it loses two one remains. What is this formula telling us?
锂原子有三个电子，如果它失去两个,剩下一个，那么这个式子告诉了我们什么？
