Here's the pneumonic I mentioned for writing the electron configuration and getting those orbital energies in the right order.

这是我提到的肺，用于写电子构型，并以正确的顺序得到轨道能量。

And I cannot have an unpaired electron in the same orbital.

我不可能在同一个轨道，得到不成对电子。

youdao

An electron. So now we have the complete description of an electron within an orbital.

电子，现在我们有了一个，轨道上的电子的完备描述。

One of the main difference is is that when you're talking about multi-electron orbitals, they're actually smaller than the corresponding orbital for the hydrogen atom.

其中最主要的区别之一,是当你讨论多电子轨道时,它们实际上，要比对应的氢原子轨道,要小一些。

So let's compare what some of the similarities and differences are between hydrogen atom orbitals, which we spent a lot of time studying, and now these one electron orbital approximations for these multi-electron atoms.

很长时间的氢原子轨道和,现在多电子原子中,的单个电子轨道近似，我们可以对比，它们之间,的相似性和不同。

So, let's write this one electron orbital approximation for berylium, that sounds like a pretty complicated question, but hopefully we know that it's not at all, 1s22s2 it's just 1 s 2, and then 2 s 2.

所以让我们写出,铍的单电子轨道近似，那听起来像是一个更为复杂的问题，但是希望我们知道它一点都不是，它仅仅是。
