So for example, if we think about fluorine, 1 s 2 2 s 2 2 p 5 that has an electron configuration of 1 s 2, 2 s 2, 2 p 5, so all we would need to do is add one more electron to get the same configuration as for neon.
比如，如果我们考虑氟原子的话，它的电子排布是，因此我们所需要做的就是给它加上一个电子,使得它与氖原子的电子排布相同。

If I want to get out right now the versions of these things, I can ask what's the value of c p 1 x, and it returns it back out.
你可以在那里看到那些,代表笛卡尔坐标点的东西，如果我想要得到现在，这个类的版本的东西的话。
-
You might be asking where the 2 p z orbital is and we'll get to that soon once we need it.
你可能会问2pz轨道在哪里,我们等会就会讲到这个问题。

The body begins to break, you get the loss of P-functioning.
身体开始损坏时，就失去人格功能性。
-
p This is going to get us dH/dp constant temperature. What is this experiment?
这帮助我们理解恒温条件下的偏H偏,那么这个实验具体是什么呢？
-
If I want to get values back out, p I could in fact simply send to that instance a message, in this case I could say p dot x.
我就是，我刚刚在这里输入的，我得到了一个c，point的实例,如果我想把值取出来，实际上我可以。
-
So, this should be pretty straight forward, 100% let's see if we can get close to a 100% on this one, which is how many radial nodes does a 4 p orbital have?
很简单,让我们来看看这题，我们是不是可以接近%,对于一个4p轨道，它有多少个节点？,给你们10秒钟？
-
We want to do that because we have too many variables here. We've already got dV p we'll get rid of p as an additional variable and replace it with V which is already in here.
我们之所以要那么做,是因为这儿有太多变量了,我们已经有了dV，我们要把,作为额外的变量消去，用已存在的V代换它。
-
I going to come back in a second to how it actually does that, but it basically says, get me x value for p 1, get me the x value for p 2, compare them, just as you would normally.
是一个类的实例,我要去取的这个实例，所关联的x值，我稍后会讲讲实际上，这里是怎么实现的，但是基本上它的意思就是，给我p1的x值。
-
But when we get to the multi-electron atoms, we see that actually the p orbitals are higher in energy than the s orbitals.
但是当我们来看多电子原子时，可以看到实际上p轨道的能量,要高于s轨道。
-
And the useful outcome of all that is that p we get to see how entropy changes with one of those variables in terms of only V, T, and p, which come out of some equation of state.
这样做的重要结果是,我们得到了熵随着V，T或者,其中一个变量变化的情况，这些可以从状态方程得到。
-
And for the s electron, since it can get closer, what we're going to see is that s electrons are actually less shielded than the corresponding p electrons.
对于s电子，因为它可以离得更近，我们可以看到s电子事实上,相对于p电子受到,更少的屏蔽。
-
So, our two glitches we see when we go from the 2 p, or from 2 s to start filling the 2 p, and then we also get another glitch when we've half-filled the 2 p, and now we're adding and having to double up in one of those p orbitals.
因此，我们的看到的两个小偏差，一个是在开始进入，2，p，轨道，或者说在填满，2，s，轨道之后,开始填，2，p，轨道的时候出现的，另一个则是在，2，p，轨道半满之后,开始继续加电子，使得其中一个，p，轨道上的。
-
And now we get the p orbitals, remember we want to fill up 1 orbital at a time before we double up, so we'll put one in the 2 p x, then one in the 2 p z, and then one in the 2 p y.
我们到了p轨道，记住在双倍填充之前,我们想要每次填充至一个轨道，所以我们在2px填充一个然后2pz填充一个，然后2py填充一个。
-
And what happens to this last p orbital is nothing at all, we just get it back.
我们会得到三个杂化轨道，最后一个p轨道。
-
T Remember, we're trying to get delta H, p we're trying to get dH/dT constant pressure and dH/dp constant temperature. OK, these are the two things were trying to get here.
想要得到在恒压状态下的偏H偏，和在恒温状态下的偏H偏,好的，这是两个我们，在这里想要得到的东西。
-
So essentially, each of these orbitals come from linear combinations of all of the original orbitals, and it's hard to picture exactly how that happens, but one that you can at least start to get an idea is if you think about combining the 2 s and the 2 p z here, which is not quite accurate because of course, we're combining all of them.
本质上，这些轨道每个都来,自原来所有轨道的线性组合，我们很难想象这是怎么发生的，但你们可以至少有个概念,如果你们考虑2s和2pz轨道的结合，这当然是不太准确的，因为我们要把所有的都组合起来。
