So it's not a continuum of energy that we can have, it's only these punctuated points of energy that are possible.
我们得到的不是一个连续的能量，而是一些分立的可能的能量值。
-
So, similarly in a case where instead we have a small energy difference, we're going to have a low frequency, which means that we're going to have a long wavelength here.
在这个例子里,能量差较小,我们得到的频率低,这意味这它的波长更长。
-
We're only using up a little bit to eject the electron, then we'll have a lot left over.
如果我们只需要用很少一部分来发射出电子，那么我们可以得到很多的剩余能量。
-
So this means that we can go directly from the energy between two levels to the frequency of the photon that's emitted when you go between those levels.
这意味着我们可以直接,从两个能级的能量得到它们之间,跃迁发射出光子的频率。
-
So, you can imagine, that we'll actually probably have a lot of kinetic energy left over if we put a lot of energy in in the first place.
因此，可以想象，如果我们一开始,就注入大量的能量,那么得到的动能也应该很大。
-
it's an easy calculation -- we're just taking the negative of the binding energy, again that makes sense, because it's this difference in energy here. So what we get is that the binding energy, when it's negative, the ionization energy is 5 . 4 5 times 10 to the negative 19 joules.
这个计算很简单-我们,只需要取结合能的负值,同样这很容易理解，因为这就是这的能量差,所以我们得到的就是结合能,当它取负值，电离能就是5。45乘以。
-
So in other words a very low energy is what we're going to have when we talk about the orbitals -- the energy of the 2 s orbital is going to be less than the energy of the 2 p orbital.
换句话说一个非常低的能量,是我们将会得到的当我们谈论轨道时,2s轨道的,能量比2p轨道,的能量低。
-
So if we don't have to hybridize one of the p orbitals, we can actually end up with a lower energy situation, because now these s p 2 orbitals are 1/3 s character, and only 2/3 p character, instead of 3/4.
我们的杂化轨道就有更多的p轨道成分，所以它们的能量更高，如果我们不杂化这个p轨道，我们可以得到一个能量更低的情况。
-
And the reason is simply because the energy that Z we gain in terms of moving up in z, 5 so from going to z equals 4 to z equals 5, -- is actually outweighed by the energy it takes to go into this new shell, to go into this new sub shell.
原因很简单,就是因为我们通过提升，所得到的能量--从，Z，等于，4，到，Z，等于，事实上比填充到这个新的壳层,新的亚壳层，所消耗的能量更多。
