No, OK and that's correct, because each photon of light actually has more energy than is needed to eject an electron.

没有，好，对了，因为每一个光子实际上,都有更多的能量去逐出一个电子。

And remember again, the binding energy physically is the negative of the ionization energy, and that's actually how you can experimentally check to see if this is actually correct.

电离能的负值，那个事实上是可以,通过实验来验证，它是否是对的,并且它等于负的。

So it looks like not too many more than half of you got this correct, so make sure you can look at your periodic table and figure out how to think about ionization energy in terms of z effective, not just in terms of memorizing what that trend is.

看起来只有一半多一点的人,做对了，所以请大家务必做到能够通过观察周期表,并在考虑电离能时,从有效核电量的观点出发，而不是仅仅依靠记住这个规律。

And, in fact, it can't even reach n, because then we would have no potential energy at all in our electron, which is not correct.

事实上，它连n都达不到，因为如果那样的话,电子就没有势能了，这是不可能的。
