So this is the idea of the octet rule that Lewis came up with way back in 1902.
这就是所谓的八隅体规则,是路易斯在,1902,年提出来的。
So, if we're talking about hydrogen, that's our one exception so far to the octet rule.
那么,如果我们讨论的是氢原子,它是目前我们遇到的八隅体规则的唯一例外。
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。
So, the octet rule is a general rule that you'll for all of the atoms.
因此,八隅体规则是一条普适的规则,对于所有原子来说都是。
So I said that we want to be talking about valence electrons here, so that means if we're talking about, for example, the octet rule for an f f molecule where we have two fluorine atoms, we need to write the valence electrons as dots around them.
我说过我们在这要讨论的是价电子,这就意味着,如果我们要讨论,比如,关于两个氟原子组成的分子的八隅体规则,我们首先需要把价电子画成围绕在它们周围的点。
