The super molecule chemistry is that small molecule units have assembled big molecule with non-covalent bond by themselves.

超分子化学是小的分子单元通过非共价键自组装成大的超级分子的化学。

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。
