So, we can say that -- if we have neon here and we want to think about what's isoelectronic, -- f minus would be isoelectronic. We also have oxygen -- what would the charge on oxygen be?

那么，我们可以说--如果我们这里有氖原子,而我们想知道与它等电子的是什么，负一价的氟离子就是与它等电子的，我们还有氧-,氧应该是几价的？

So, we can say that -- if we have neon here and we want to think about what's isoelectronic, -- f minus would be isoelectronic. We also have oxygen -- what would the charge on oxygen be? Um-hmm, right. 2 minus.

那么，我们可以说--如果我们这里有氖原子,而我们想知道与它等电子的是什么，负一价的氟离子就是与它等电子的，我们还有氧-,氧应该是几价的？没错，负二价。
