And that's going to be equal to the negative the binding energy of 2 s in b, in neutral boron.

它应该等于中性硼原子中,2，s，电子的束缚能的负值。

And what we say when we talk about the delta energy is I E 2 that this is going to be equal to i e 2, or the second ionization energy, or we could say the negative of the binding energy of a 2 s electron in b plus.

那么我们说,Δ，E，应该等于，或者说第二电离能，也就是正一价硼中，2，s，电子的,束缚能的负值。
