So, if we're going to go to the moon, we're going to go to Mars, we want to be able to produce oxygen, structural metals and photovoltaic materials from in situ resources.

如果我们要去月球上，我们要去火星上，我们则必须要制造，氧气，结构金属和光电材料，就在原地制造。

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？
