S — we don't have to hybridize it, it already has only one unpaired electron in a 1 s orbital.

s -我们不用杂化它，它已经有而且仅有一个未配对电子在s轨道里。

youdao

So, our first orbital that an electron 1 s must be coming from is the 1 s.

所以，我们的第一个肯定有电子，被打出的轨道是。

youdao

So if we write the electron configuration you see that this is the electron configuration here, 1s22s22p 1 s 2, 2 s 2, 2 p 6, 3s1 and now we're going into that third shell 3 s 1.

现在我们来到第三层,你们会看到3s1价电子之间的区别，电子构型是，现在我们来到第三层。

youdao

For example, for the 2 s, again what you see is that the multi-electron atom, its 2 s orbital is lower in energy than it is for the hydrogen.

举例来说对于2s轨道，在多电子原子，中可以看到，它的2s轨道的能量低于氢原子的。
