l l So what you can do for a 1 s is just take 1 minus 1 and then l is equal to 0, so you have zero radial nodes.
它等于1减去,是等于0的,所以没有节点,这和我们看到的是相符的。

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.

So, you should know that there's four radial nodes, right, we have 5 minus 1 minus l -- is there a question?
你们要记住这里有四个节点,对吧,5减去1减去l,有问题吗?
How many bonding electrons does c l have? All right. Let's see, we've got a mixed response here, it turns out it has two bonding electrons.
氯有多少成键电子?好,让我们来看看,大家的回答不太一致,结果应该是两个成键电子。
And the last example that we're going to talk about is thionyl chloride, so it's s o c l 2. This is another good step forward, because now we actually have four different atoms in our molecule.
我们要讨论的最后一个例子,是氯化亚砜,就是硫,氧,氯,二,这又是一个进步,因为我们的分子中现在有四个不同的原子了。
So I show that here, so in green, you have what's called a carboxcylic acid group, a c o o h, which gets converted by s o c l 2 to a c double bond o c l or an acid chloride.
我在这里用绿色表示,我们所说的羧酸族化合物,碳,氧,氧,氢,它被亚硫酰氯转化为,一个碳氧双键与碳氯单键组成的酰氯。
So when we talk about p orbitals, it's similar to talking about s orbitals, and the difference lies, and now we have a different value for l, so l equals 1 for a p orbital, and we know if we have l equal 1, we can have three different total orbitals that have sub-shell of l equalling 1.
当我们考虑p轨道时,这和s轨道的情形和相似,不同之处在于l的值不一样,对于p轨道,l等于1,我们知道如果l等于1,我们有3个,不同的轨道。
And the first is l, and l is angular momentum quantum number, and it's called that because it dictates the angular momentum that our electron has in our atom.
第一个就是l,l是,角动量量子数,叫它这个名字,是因为它表明,原子中,电子的角动量是多少。
And when we talk about l it is a quantum number, so because it's a quantum number, we know that it can only have discreet values, it can't just be any value we want, it's very specific values.
当我们讲,l是一个量子数时,因为它是量子数,我们知道,它只能去分立的值,它不能取到所有的数,它取一些确定的数。
s We are back over to E as a function of n, l, m and s, only we got there through this other torturous route.
我们回到将E作为函数n,l和,只要我们解决了这个烦人的路径。
So let's think about lists. So if l is a list, l sort I can call something like s dot sort, l dot sort.
所以让我们想想链表,所以如果l是一个,链表我可以调用像是s,sort的函数。
