So I mentioned you should be able to identify both how many nodes you have and what a graph might look like of different radial probability distributions.

我说过你们要能够辨认,不同的径向概率分布有多少个节点,以及它的图画出来,大概是什么样的。

So let's do a quick clicker question, and you tell me how many valence electrons does fluorine have? Remember, valence electrons are different from core, they're only the outer-most electrons in the outer-most shell.

那么让我们来做一个小选择题，请大家来告诉我,氟有多少个价电子，要记得，价电子与芯电子不同，它们是在最外壳层的最靠外面的电子。

So the point is, this balance between energy thatyou could think of as say bond energies in chemical reactions, and entropy that you can think of in terms of disorder, how many different possible combinations or configurations of something wrong, will dictate where the equilibrium lies.

关键在于，这种能量与熵之间的平衡,确定了平衡的条件，在化学中能量涉及键能，而熵和无序有关,即有多少可能的不同组合或者形位，二者的平衡会告诉我们平衡态是什么样子。

So, how many distinct, so again, we're talking about distinct kinetic energies, a spectrum for the element hafnium, 72 and I'll tell you here that it has a z of 72, so you don't have to spend two minutes searching your periodic table.

好，有多少分立的……还是一样，我们讨论的还是不同的动能，铪元素的光谱中出现，而且我来告诉大家铪的原子序数是，这样你就不用因为在元素周期表中找它,而花费两分钟的时间了。

So if we say that we have a 2 p orbital here, that means that we can have 2 how many different complete orbitals have a 2 for an n, and a p as its l value? three.

如果我们说这里有一个“2p“轨道，那就意味着我们有,多少完全不同的轨道对于n有一个,而且对于l值有一个p？3个。
