So, presumably, if we follow our rules so far only one of these should be correct.

那么，可以假定，如果我们按照之前的规则,应该只有一个是正确的。

The natural laws for Hobbes are not divine commands or ordinances, he says, but they are rules of practical reason figured out by us as the optimal means of securing our well-being.

对霍布斯来说，自然法不是神圣的法令,或者条例，但这些是,我们发现的实践理性的法则,就像一种最佳的方式保护我们的幸福生活。

Step three in our Lewis structure rules is to figure out how many electrons we would need in order for every single atom in our molecule to have a full valence shell.

路易斯结构规则的第三步是,找出让分子中每个原子的价壳层,都排满应该需要多少个价电子。

So, let's go ahead and draw our Lewis structure based on the rest of the rules now that we have a skeleton.

那么，让我们继续画我们的路易斯结构,看看在得到骨架之后还有哪些规则。

So, our second step, as we go through our Lewis structure rules, is to figure out how many valence electrons we have in our entire molecule.

那么，我们的第二步，按照路易斯结构的规则，应该是判断在整个分子中,包含多少个价电子。

So, remember, boron was one of those exceptions to our Lewis structure rules where it was perfectly happy not having a full octet.

所以我们可以加上3个氢原子,对于BH3，这是个稳定结构,记住，B是Lewis结构的一个特例。

So we have two electrons in our bonding orbital, but because we use the same rules to fill up molecular orbitals as we do atomic orbitals, so the Pauli exclusion principle tells us we can't have more than two electrons per orbital, so we have to go up to our anti-bonding orbital here.

所以在成键轨道上有两个电子，但因为我们用了和原子轨道时,用的相同的规则，所以Pauli不相容原理告诉我们,一个轨道上不能有两个以上的电子，所以我们需要填充到反键轨道上去。
