If we have a higher z effective, it's pulled in tighter, we have to put in more energy in order to eject an electron, so it turns out that that's why case 2 is actually the lowest energy that we need to put in.

而如果有效核电量更高，原子核的束缚也就更紧，我们不得不输入更多的能量来打出一个电子，这就是第二种情况,所需要输入的,能量更少的原因。

The z effective is lower, so we have to put less energy in to get an ion out.

它的有效核电量更低，所以我们只需要更少的能量就能打出一个离子。

They get into these fights and screaming matches and name-calling and such even if it's not physical violence.

他们大打出手,声嘶力竭的辱骂对方,即使没有身体暴力。

The typing coming from here is going at that rate, being Stanford alumni, of course the first thing you could type here would be Shakespeare.

打字的速度就是这样，作为斯坦福的校友，我想大家能够想打出的第一个便是，莎士比亚。

I'll show you some other advertisements later that are oriented to men that make that same argument: that if you're a man, nobody is going to tell you what to eat.

我会再给你们看一个广告,也是瞄准男性观众打出了同样的旗号,如果你是个男人,没有人可以左右你该吃些什么

So, which has the smallest energy that you have to put in in order to eject this electron?

也就是，哪一项为了打出一个电子,所需要注入的能量最少？

So in the case of 12 32, that is our highest kinetic energy, it's the smallest amount of energy it takes to pop an electron out of that orbital.

因此，1232是我们能够得到的,最高的动能，它是从这个轨道中,打出一个电子需要消耗的最低能量。

So, our first orbital that an electron 1 s must be coming from is the 1 s.

所以，我们的第一个肯定有电子,被打出的轨道是。

now we're not just talking about 1 photon, 1/2 let's say we shoot them all at the same time at our metal, each of them having some energy that's let's say 1/2 the work function. So, just to take a little bit of an informal survey, who thinks here that we will have an electron that is ejected in this case?

我们现在不仅仅讨论一个光子，它们所具有的能量是功函数的，我们在同一时刻把它们打到金属上,我们做一个不太正式的调查,谁认为这种情况下,一个电子会被打出？

Remember, because that 1 s orbital is all the way down in terms of if we're thinking about an energy diagram, we're all the way down here, so we have a huge amount of energy we have to put into the system in order to eject an electron.

还记得吧，因为1，s，轨道在能量示意图里,是在最底部的，我们要一直到最下面，所以我们要向这个系统注入非常大的能量,才能打出一个电子。

So what we'll end up with is boron plus, 1 s 2 2 s 2 1 s 2, 2 s 2, E and what we say is the delta energy or the change in energy as the same thing as saying the energy of the products minus the energy of our reactant here, that's how much energy we have to put into the system to eject an electron.

所以结果应该是正一价的硼，电子排布为，我们说，Δ,也就是，E，的变化量,等于生成物的能量,减去反应物的能量，这就是我们从这个系统中,打出一个电子所需要的能量。
