他忽略了所有非价层电子。

And he's stripped off all of the non-valence electrons.

因为它不是价层电子，所以忘记它吧。

Because it is not the valence shell. Forget about it.

三维结构配位聚合物的自聚焦或自散焦效应主要受中心金属离子价层电子构型的影响。

Three dimensional coordination polymers show self defocusing or self focusing effects depending on the valence shell structures of the central ions.

So in terms of total numbers that we would need to complete our octets and fill our valence shells, we would need 18 electrons.

因此要填满我们的“八隅体“,排满所有的价壳层，我们总共需要十八个电子。

The reason is because we already have a full valence shell for our hydrogen, it doesn't want any more electrons.

原因是因为我们的氢,已经有一个排满的价壳层了，它不再需要多余的电子了。
