The results show that the hydrogen of C—H bond on ACFs were substituted by fluorine at different condition. The C—F covalence bond was built at molecular level.

结果表明，随着反应时间和温度的变化，活性炭纤维表面氟取代氢基数目增加，同时在分子水平上形成C—F 共价键。

Whereas for fluorine, fluorine is smaller than f minus is the one that's the outer shell shown here.

而对于氟来说，氟原子更小,与外部壳层在这的负一价氟离子相比。

So, we see is when we use the octet rule to look at fluorine molecule, we're combining two fluorine atoms, and what we end up with is an f f molecule where they're sharing two electrons, so making that covalent bond.

那么，我们看到把八隅体规则用到氟分子上,就是把两个氟原子组合起来，最终得到的氟分子中两个原子,共用一对电子，这就构成了共价键。

There is a striking parallel here in that the group one elements have a tendency to want to give up electrons, F Cl Br whereas the fluorine, chlorine, bromine, have a tendency to attract electrons.

这儿有高度的相似性,每个组都有,失去电子的趋势的，相反的，则是有得电子的趋势。
