So, let's see how some of this works, and hopefully your counterparts from 100 years ago would also be able to think about how this works, even if they don't have the quantum mechanics behind the individual electron configurations for atoms.

那么，下面让我们来看一下它是怎么用的，希望一百年前想你们一样的同学,也能够弄懂它为什么能用，尽管他们没有量子力学,不知道原子的电子排布。

But they're not accurate all the time in predicting bonding within molecules, and the reason for this is because Lewis structures are not, in fact, based on quantum mechanics.

但它们在预测分子内,成键时不总是正确的，这是因为Lewis结构，实际上不是基于量子力学的。

So these names, they don't really make any sense why they're called past s p and f, and it turns out that it comes from spectroscopy terms that are pre-quantum mechanics where, for example, this is called the sharp line, I think the principle, the diffuse, and the fundamental.

看到这些名字，你会发现,它们为什么叫s，p，f是没什么道理的，事实上,它们来源于,量子力学之前的光谱学中的术语，例如，它们分别叫做锐线，我认为是主线，漫射和基本。
