So let's do a quick clicker question, and you tell me how many valence electrons does fluorine have? Remember, valence electrons are different from core, they're only the outer-most electrons in the outer-most shell.
那麽讓我們來做一個小選擇題，請大家來告訴我,氟有多少個價電子，要記得，價電子與芯電子不同，它們是在最外殼層的最靠外麪的電子。

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.
我在這裡想要指出的是,儅大家在看這些數字的時候，最重要的是，要看到這些,巨大的差異,看到所謂價電子，即外層電子的電離能與，1，s，軌道，電離能之間的巨大差異。
