PROFESSOR: No. So, compared to the atoms, it should be somewhat the same energy, we shouldn't get any extra stabilization from forming the molecule.

不会，所以和原子相比，它的能量相同，形成分子并不会带来额外的稳定性。

All right. So formal charge can actually help us out when we're trying to decide between several Lewis structures that look like they might be comparable in terms of which might be the lower energy or the more stable structure.

好的，形式电荷真的可以,帮助我们决定,在几种路易斯结构中,哪个更可能符合能量更低,或者结构更稳定的要求。

Alumina is really stable, which is why it takes so much energy to make aluminum.

矾土相当稳定，这就是为什么需要消耗大量的能量制备铝了。

So, if we have energy that's released, would you say that the chlorine ion is more or less stable than the chlorine atom?

那么，如果我们放出了能量，你认为氯离子比氯原子,更稳定还是更不稳定呢？

At some point you're going to hit a well here, which is the point where it's most stabilized or at its lowest energy.

直到某一时刻，你会到达这个势阱，也就是体系最稳定,或者说能量最低的位置。

But we see if we have a free electron, as we do in this dotted line here, that's going to be a higher energy that's less stable.

但是我们看到如果,我们有一个自由电子，就像虚线所示那样，那将会是一个较高的,不够稳定的能量。

Those are going to be the more stable or the lower energy structures.

这种结构应该是更稳定的,或者能量更低的结构。

So, if we want to go from that stable state to that less stable state, we need to put in a certain amount of energy to our system, that difference between the free electron and the electron bound to the metal.

所以，如果我们想使电子,从稳态到达不够稳定的状态，我们需要引入一定数量的,能量到系统中，即自由电子和束缚于金属的,电子的能量差。

We knew from Friday, when we talked about energy, that ground state was that n equals 1 value, that was the lowest energy, that was the most stable place for the electron.

我们上周五知道了，在讨论能量的时候，基态指，n等于1的态，它能量最低，是，最稳定的态。
