So what I want to point out when you're kind of looking at these numbers here, what the significance is, look at that huge difference between what the ionization energies are for what we call those valence electrons, -- those outer shell electrons, those are core electrons there.

我在这里想要指出的是,当大家在看这些数字的时候，最重要的是，要看到这些,巨大的差异,看到所谓价电子，即外层电子的电离能与，1，s，轨道，电离能之间的巨大差异。
