We started talking about these on Wednesday, and what we're going to start with is considering specifically the wave functions for multi-electron atoms.

我们从周三开始讨论这些，而且我们将要以特别地考虑,多电子原子的波函数,为开始。

So when you operate on the wave function, what you end up with is getting the binding energy of the electron, and the wave function back out.

所以当你将它作用于波函数时，你得到的是电子的结合能,和后面的波函数。

And when we take the wave function and square it, that's going to be equal to the probability density of finding an electron at some point in your atom.

当我们把波函数平方时，就等于在某处,找到一个电子的概率密度。

And we can also write this in an even simpler form, which is what's called electron configuration, and this is just a shorthand notation for these electron wave functions.

而且我们也可以将它，写为一个更简单的形式，它叫做电子构型,这个仅仅是这些电子波函数的。

So we can do this essentially for any atom we want, we just have more and more wave functions that we're breaking it up to as we get to more and more electrons.

所以我们基本上对，任何一个原子都可以这么做,我们仅仅会有越来越多的波函数,因为我们将它分为越来越多的电子。

We can do the exact same thing when we talk about lithium, but now instead of breaking it up into two wave functions, we're breaking it up into three wave functions because we have three electrons.

在讨论锂时,我们也可以做，完全相同的事情,但不是把它分为两个波函数，而是分为三个波函数,因为我们有3个电子。

But right now, what I want you to be thinking of a wave function as is just some representation of an electron.

但是现在，我想让你们,将波函数仅仅理解为,一个电子的表示方法。

But before we get to that, in terms of thinking just think, OK, this is representing my particle, this is representing my electron that's what the wave function is.

但是在我们谈论那个部分之前，在理解方面，仅仅是理解，好的，它代表了粒子，它代表了电子,这就是波函数。

So we do, in fact, have a dependence on what the angle is of the electron as we define it in the orbital.

实际上当我们定义电子在这个轨道,它的波函数的确是和角度有关的。

So, the wave functions for multi-electron atoms.

所以，对于多电子原子的波函数。

So, as an example, let's take argon, I've written up the electron configuration here, and let's think about what some of the similarities might be between wave functions in argon and wave functions for hydrogen.

所以作为一个例子我们来看看氩，我已经把它的电子构型写在这里，我们来考虑氩和,氢波函数之间的,一些相似性。

So on Friday, we'll start with talking about the wave functions for the multi-electron atoms.

在周五，我们要开始讨论,多电子原子的波函数。

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 we have the operationon the wave function in terms of r, theta, and phi and remember this e is just our binding energy for the electron, and we get back out this wave function.

我们用r，θ，φ来表示,将算符作用于波函数,而且记住e仅仅是电子结合能，然后后面加上波函数。

And when we describe this in terms of talking about chemistry terminology, we would call the first one the 1 s, and 1 is in parentheses because we're talking about the first electron there, and we would multiply it by the wave function for the second one, which is also 1 s, but now we are talking about that second electron.

当我们用化学术语来,描述它的时候，我们称第一个为“1s“,括号中的1是因为我们,在谈论第一个电子,而且我们会用它的波函数，乘以第二个,第二个也是“1s“,但是我们现在谈论的是,第二个电子。
