to the n, every value in the 1 bit vector we looked at last time is either 0 or 1. So it's a binary n number of n bits, 2 to the n.
从2到n，我们上次看到的,位向量的每个值不是0就是,所以它是n，比特的二进制数,从2到。

-
So what we end up with is one radial node for the 2 s orbital of hydrogen, and we can apply that for argon or any other multi-electron atom here, we also have one radial node for the 2 s orbital of argon.
那意味着它们都是径向节点,所以我们得出的结论是，氢的2s轨道是1个径向节点,我们可以将它应用，到氩或者任意一个多电子原子,对于氩的2s轨道。
-
s So this is the 1 s, you can look it up if you're interested 5s for the 2 s, or 3 s, or 5 s, or whatever you're curious about.
这是，如果你们感兴趣,你们可以找找2s或者3s或者，或者任何你感兴趣的轨道。
-
So it's 2 to the 32, 'cause remember a bit is a 0 or 1.
就是2的32次方，因为1比特只能表示0或。
-
So if I have 32 bits, each of which can be a 0 or 1, that's two possibilities for every place, so 2 to the 32, that's 4 billion.
如果有32比特的话，每个比特都有0或，两种可能性，所以是2的32次方，也就是40亿。
-
px We'll call it either pi 2 p x, 2py if we're combining the x orbitals, or pi 2 p y.
我们叫它π,如果是x轨道组合的话，或者π
-
And an important thing to remember when we talk about resonance hybrids is that the structure it's not 1/2 the time this structure, and 1/2 of the time this structure, it's actually some combination or some average between the two structures.
而当我们讨论共振杂化的时候,有一件重要的事情需要牢记,那就是这种结构并不是,一半时间处于这种结构的状态，而另外一半时间又变成了这种结构的状态，它实际上是两种结构在,一定程度上的组合或者平均。
-
When we talk about the n equals 2 state, we now have 2 squared or 4 degenerate same energy orbitals, and those are the 2 s orbital.
当考虑n等于2的态时，我们有2的平方,或者4个简并能量的轨道，它们是2s轨道。
-
It's always a good first approximation, because you need to start somewhere in terms of drawing Lewis structures, but then if you go and figure out the formal charge and you just have lots of charge separation or very high charges, like a plus 2 and a minus 2 and a minus 1 all different places in the atom, what it should tell you is maybe there's a better structure.
它总是一个好的第一近似，因为在画路易斯结构的时候,你总需要一个起点，但是如果你在算出形式电荷之后,发现有很多电荷分开了,或者说有很高的电荷，比如有一个正二，一个负二，还有一个负一1,在原子的各个地方，这应该就是在告诉你,或许还有一个更好的路易斯结构。
-
Nothing is said of Moses' childhood, But we learn of his awareness of his Israelite identity, or his identification with the Hebrews, in the following passage: this is in Exodus 2:11-15: Some time after that, when Moses had grown up, he went out to his kinsfolk and witnessed their labors.
丝毫没有提到摩西的童年，但是我们却知道他意识到自己以色列人的身份，或者是他与希伯来人的身份关联，在接下来的《出埃及记》第2章11到15节中：,在那之后，摩西长大了，他出去看到了他的同族和他们的劳作。
-
We're getting further away from the nucleus because we're jumping, for example, from the n equals 2 to the n equals 3 shell, or from the n equals 3 to the n equals 4 shell.
我们将会离原子核越来越远,因为我们在跃迁，比如从，n，等于，2，的壳层到n等于，3，的壳层，或者从，n，等于，3，的壳层到n等于，4，的壳层。
-
So let's look at the first case 2px where we have either the 2 p x or 2 p y type of orbitals that we're combining.
让我们看看第一个情形,我们要组合,或者2py轨道。
-
2 So what we end up saying is that the z effective or the effective charge that that first electron feels is now going to be plus 2.
第一个电子感觉到的有效的z或者有效电荷现在是,我们再一次将它带入我们的方程。
-
And when we make these comparisons, one thing I want to point out is that we need to keep the constant principle quantum number constant, so we're talking about a certain state, so we could talk about the n equals 2 state, or the n equals 3 state.
当我们做这些比较时，我想指出的一件事是,我们需要保持常量原则,保持量子数是常数，所以我们在讨论一个确定的态时，我们可以谈论n等于2的态，或者n等于3的态。
-
You know, if you're wandering through Harvard Square and you see an out-of-work Harvard grad, they're handing out examples of square roots, they'll give you an example and you can test it to see is the square root of 2, 1.41529 or whatever.
你知道，如果你从哈佛校园里穿过去,你看见了一个失业校友，正在派发平方根的示例，他们会给你一个例子,而你会检查2的平方根是1。41529或者别的什么。
-
So another way to say that is, in a sense, if we're thinking about the excited state of a hydrogen atom, the first excited state, or the n equals 2 state, what we're saying is that it's actually bigger than the ground state, or the 1 s state of a hydrogen atom.
换句话说，如果我们激发一个氢原子，第一激发态或者说ｎ等于２的态，我们说它比氢原子基态,或者说１ｓ态要大。
