However, on Friday we will use a different approach so we can talkabout bonding within atoms that have more than two atoms, molecules with more than two atoms.

但是，在周五我们,会用一种新的办法来讨论,不止两个原子的分子的成键。

However evil those books are in and of themselves, we have to read them so that we might see and know and yet abstain.

但是邪恶也藏在这些书中，我们不得不读它们以便能看到并了解它们然后将之弃绝。

So, we were talking, however, about energy in terms of electron affinity, so we can actually relate electron affinity to any reaction by saying if we have this reaction written as here where we're gaining an electron, we say that electron affinity is just equal to the negative of that change in energy.

但是，我们现在讨论的能量,是电子亲和能，因，此我们可以将电子亲和能,与任何反应联系起来,只要我们将反应写成这种得到电子的形式，我们说电子亲和能就等于,反应前后能量变化的负值。

We can still hybridize all these orbitals, however, so we can still form four hybrid orbitals, which are again, 2 s p 3 hybrid orbitals.

但我们仍然可以杂化这些轨道，所以我们还是可以形成4个杂化轨道，同样的，是2sp3杂化轨道。
