This week, I’m reading about a lithium ion-based energy storage grid in Johnson City, N.Y.

本周，我关注着在纽约州约翰逊市进行的一项基于锂离子的储能网络研究。

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。

So, why don't you take a look at this and tell me which are possible for a 2 s electron in a lithium atom where z 3 is going to be equal to three?

你们为什么不看一下这个然后告诉我对,于一个锂原子中的2s电子哪些是可能,的？它的有效电荷量,可能等于？
