And what does that first orbital subshell, that s-shell, look like?

第一个轨道子壳，那个 s-壳，是什么样子的？

I guess in each of the geometric configurations for each subshell, you can put two electrons.

我想在每个子壳的每个几何配置中，您都可以放置两个电子。

It fills the first energy shell and that first subshell, which is the S-shape.

它填充第一个能量壳和第一个子壳，即 S 形。

You only have one electron in the s subshell of the first energy shell.

在第一个能量层的 s 子层中只有一个电子。

So in the s subshell within the first period or the first energy shell, it has two electrons there. Fascinating. So what about lithium?

所以在第一周期或第一能量壳内的 s 子壳中，它有两个电子。迷人。那么锂呢？

Well, in each of these subshells-- and I'll be a little bit more specific in probably the next video, because I'm pretty much out of time-- you can put two.

好吧，在这些子外壳中的每一个中——我可能会在下一个视频中更具体一点，因为我几乎没时间了——你可以放两个。
