So chlorine, if we talk about it in terms of electron affinity, we would be writing that we're actually gaining an electron here, and getting the ion, c l minus.

那么，氯，如果我们要讨论它的电子亲和能，我们会假设它真的得到了,一个电子而变成离子，负一价的氯。

It turns out there's a new function strlen S-T-R-L-E-N that you probably have not used yet called strlen, S-T-R-L-E-N, programmers early on and still like to be succinct but communicates sufficiently what they mean.

结果这里有个新的函数,你可能没有使用过，叫做，早期的和现在的程序员喜欢简洁地,但是能充分的传达他们的意思。

Didn't create a new list. The old l is still there but it's different than it used to be.

它改变了数组，而并没有新建一个数组,老数组l依旧存在。

And when we talk about angular nodes, the number of angular nodes we have in an orbital is going to be equal to l.

当我们谈到角向节点时，一个轨道的,角向节点数等于ｌ

In the Savings and Loan crisis it was a certain segment of the banking community--the S&L's that seemed to be in trouble but it didn't seem to be then a house of cards that could spread around the country and around the world.

在储贷危机中，只是银行机构中的,一个特定部分-储蓄和存款,陷入了困境,但是这似乎不是一个,能够延伸至整个国家,和整个世界的不切实际的无法实现的计划。

And, if we go to n equals two, this would be the l shell.

而当n等于2时，也就是L层。

That has to be the case because l equals for s orbitals.

这是因为对ｓ轨道ｌ等于０．

So, if we think of just an example, 2 we could say that 4 l equals 2, what would be our lowest value of m sub l?

举个例子，如果我们说l等于，那m小标l，最小值是多少？

麻省理工公开课 - 化学原理课程节选

So the allowed values for m sub l 0 are going to be negative l, all the way up to 0, l and then up to positive l.

所以m小标l的可能值,是从负l，一直到，然后到正。

So, our next level up that we can go is going to be the n equals 2 energy level, but we also have an l and an m value, 0 so our lowest l is going to be a there.

所以下一个能量,是n等于2的能级，但我们还有l和m的值，所以我们最低的l等于。

So finally, if we talk about our last example of when n is going to be equal 2, l -1 and then minus 1 for m.

最后我们要讲的,这个例子，是n等于2时，等于1，we，can，have，2，，1，for，l,而m等于。

So, it would be a good question to ask n why are we limited clearly there's this relationship between l and n, and we can't get any higher than n equals one.

那我们要问了,为什么我们被限制了，很明显，l和,有关系，为什么不能取到，n-1更大的值。

So since it's a component of the angular momentum, that means that it's never going to be able to go higher than l is, so it makes sense that, for example, it could start at and then l go all the way up to l.

因为，它是，角动量的分量，这意味着，它不会，比l大，这是很容易理解的，比如说，它可以从零开始,一直到。

By the way, l equals one would be the p-orbitals.

顺便说一下，l等于1时就到了p轨道的范围。
