So we can actually pop an electron or eject an electron from any single orbital that is occupied within the atom.

任何一个被占据轨道,打出一个电子,或者说发射出一个电子。

And they type in "cappuccino" on a little terminal, which is basically a calculator on top of the cash box, and then they get $3.24 from that. They get a receipt.

他们在一个小终端机上输入“卡布奇诺“,那个终端机不过是个收银盒上价格计算器而已，他们划走了3。24美元，打出一张凭条。

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。

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, 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。

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。

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, for example, it's not just the 2 p that we could actually take an electron from, we could also think about ejecting an electron from the 2 s orbital.

比如，我们不只可以从，2，p，轨道上,打出一个电子，还能考虑从，2，s，轨道上,发射出一个电子。
