So, what we have left in our equation is only one part that n we haven't explained yet, and that is that n value.
现在方程里只剩下一个常数,我们还没有解释，这就是。
-
And again, our energy is going to be the same where we again only depend on the n value.
同样的能量，和以前一样,因为它,只决定于n的值。
-
OK. What does that say? I'm going to change MinIndex min index to also point there n value is 8, j starts off here, and I say, OK, is the thing I'm looking at here smaller than that? Yes.
好的，这意味着什么？,我打算交换，让它也指向那里，MinVal是8，j从这里开始,我要找的值比这个小么？是的。
-
I declare a variable called n. I'm not giving it a value yet, so I had better be careful.
我申明一个变量n，我先不给它赋值，所以我最好小心点。
-
We go to n equals two for a fixed value of Z.
我们对于一个给定的Z值，让n等于。
-
And I want to really highlight here we're talking about for a hydrogen atom orbitals - with the same n value have the same energy.
我想强调的是,我们所说的,都是对单个的氢原子,和言的,对于同样的n值能量相同。
-
Again, the reason for that is because the energy only depends on the n value here, it doesn't depend on l or on m.
因为，能量,只和n的值有关，与l和m的值无关。
-
So if we're keeping n the same, we look and what we saw was that size actually decreases as we increase the value of l.
如果我们保持ｎ不变，我们看到随着ｌ值的,增大尺寸变小。
-
If we have n equals 4, what is the highest value of l that we can have?
如果ｎ等于４,ｌ的最大值是多少？
-
Ah, n times, because for each value of i, I'm going to do that m thing, n*m so that is, close to what you said, right?
因此这就和你说的差不多了对不对？,这个问题的复杂度为，让我写下来，是-对不对，是？
-
We knew from Friday, when we talked about energy, that ground state was that n equals 1 value, that was the lowest energy, that was the most stable place for the electron.
我们上周五知道了，在讨论能量的时候，基态指，n等于1的态，它能量最低，是，最稳定的态。
-
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 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。
-
And unlike n, l can start all the way down at 0, and it increases by integer value, so we go 1, 2, 3, and all the way up.
不像n，l可以从0开始取，然后每次增加一个整数，所以我们可以去1，2，3，一直下去。
-
This should make sense to you, because they don't, in fact, want to gain another electron, because that would mean that electron would have to go into a new value of n, a new shell, and that's really going to increase the energy of the system.
这对大家来说应该容易理解，因为它们实际上不想得到另一个电子，因为这意味着这个电子不得不,到一个新的，n，值更大的壳层上去，这将会增加系统的能量。
-
But also unlike n, l cannot have just any value, we can't go into infinity.
但不像n，l，不能取所有整数，不能到正无穷。
-
Core electrons are all those electrons held in really tight with the nucleus in the inner shells, whereas the valence electrons are only those electrons that are in the outer-most shell, or at your highest value of n of the principal quantum number.
芯电子是那些,在内壳层被原子核束缚得非常紧的电子，而价电子只包括,最外层的电子，或者说主量子数，n，的值最大的那些电子。
-
This first number here gives the value of n.
这里的第一个数字是n的值。
-
That's why in the earlier models of the atom, they're not horrible to sometimes think about just each n value as a little ring around.
这就是为什么在早期原子模型中，人们没有感觉到把每一个，n，都想象成,一个绕核的小圆圈有什么不妥。
-
So what's our value for n here?
是的对的？
-
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。
-
The other main difference that we're really going to get to today is that in multi-electron atoms, orbital energies depend not just on the shell, which is what we saw before, not just on the value of n, but also on the angular momentum quantum l number. So they also depend on the sub-shell or l.
我们今天要讨论的,另一个很重要的区别就是,在多电子原子中，轨道能力不仅仅依赖于，我们以前看到的外层，不仅仅依赖于n的值，而是与角动量量子数也有关系,所以它们也依赖于亚外层或者。
