That is to say the ionizationenergyof the second most electron.
这是二级电离能,这就是说,电子数第二多的电离能。

But, in fact, we can also talk about the ionizationenergyof different states of the hydrogen atom or of any atom.
但实际上我们也可以讨论氢原子,或者其它任何原子的其它能级的电离能。

So, what we call this is the third ionizationenergy, or the negative of the binding energy, again of the 2 s orbital, but now it's in boron plus 2 to we're starting with.
