I said what hold the bonds together, what holds two atoms together is the attractive force we have between each electron and the other nucleus.

我说过什么将它们结合在一起，将两个原子结合在一起的是一个吸引力,其中一个原子中的电子与另一个原子中的原子核之间。

And, in any arbitrary crucible full of molten silver, half of them are going to be spin-up and half of them are going to be spin-down.

并且，在任一个浇满了熔银的坩埚中，银原子中的电子一半是向上转,另一半是向下转。

So now that we can do this, we can compare and think about, we know how to consider wave functions for individual electrons in multi-electron atoms using those Hartree orbitals or the one electron wave approximations.

现在我们可以做这些了，我们可以对比和考虑，我们知道如何用哈特里轨道,或者单电子波近似去考虑,多电子原子中的单个电子波函数,所以对于我们研究了。

So, why don't you take a look at this and tell me which are possible for a 2 s electron in a lithium atom where z 3 is going to be equal to three?

你们为什么不看一下这个然后告诉我对,于一个锂原子中的2s电子哪些是可能,的？它的有效电荷量,可能等于？

Pauli So, here, Pauli came out on top, we say, and he's known for the Pauli exclusion principle, which tells us that no two electrons in the same atom can have the same four quantum numbers.

在这里是，他因为Pauli不相容原理而出名，这个原理是说同一个原子中的两个电子,不能有相同的第四量子数。
