So what we're going to do is set these two things equal to each other, put in stars here.
我们只需要令这两个表达式相等,在这里标注上*号

Yeah. So we have two orbitals, or four electrons that can have that set of quantum numbers.
嗯，有我们有两个轨道，也就是４个电子可以有这套量子数。

So if I wanted to represent, for example, this is the set two, six and eight, I put a one in those slots.
所以如果我想表示的话，比如，这是2，6，8的集合，我放置一个数在这个位置中。

What I though I'd do is just tease you with some visuals if you haven't gotten to the point of playing with the staff solution so the themes of problem set 3 are two-fold.
如果你们还没达到使用解决方案的程度,那现在我能做的就是用一些图形为你们梳理一下,习题集3的主题,是两方面的。

He has two electrons here with the same set of quantum numbers. B but these are two separate hydrogen atoms.
因为我写了两个量子数,一样的电子,但这是在两个不同原子中啊。
-
If I want the values two, six and eight in there, I would do an insert of two into that set, an insert of six into that set, and an insert of eight into the set.
如果我想让值2，6，8在那个位置，我会把2插入到那个集合中，把6插入到那个集合中，把8插入到那个集合中。

So, let's change our graph where we now have this zero point set as the two individuals hydrogen atoms, and then we see that our h 2 molecule is at the negative of the dissociation energy, or the negative what that bond strength is.
那么让我们把曲线图中的零点能改到,两个分离的氢原子处，那我们就会看到,氢分子就是负的离解能，或者负的键的强度。
-
Because we have paired set in a 2 s orbital, so all we're left essentially is two electrons that are available for bonding.
因为我们有一对，在2s轨道里已经配对了,所以只剩下两个电子可以用来成键。
