And we put up this hypothesis that our observation is that octet stability seems to be an attractive electron configuration.
我们把假设置于我们的观察之上,即8电子稳定体系,似乎是一种吸引人的电子图像。
OK, last day, you talked about the Born-Haber cycle, and octet stability via electron transfer.
言归正传,昨天我们讲的是伯恩哈勃循环,和8电子稳定结构。
What bothers Socrates most about our democracy is a certain kind of instability, its tendency to be pulled between extremes of anarchy, between lawlessness and tyranny.
苏格拉底对我们民主最感困扰的是,不稳定性,倾向于失序两端,拉扯的特性,即介于目无法纪与专制之间。
Iron as an element is a solid. That's it's most stable state at room temperature and pressure, right, and so on. And then we can figure out heats of formation.
铁单质是固态,这是他在室温和常压下,最稳定的状态,然后我们,可以算出生成热,现在这个。
So what we see is that structure a is the most stable because we have the least separation of charge in the case of structure a.
因此我们看到结构,A,应该是最稳定的,因为这种情况下,分开的电荷最少。
So far, we've put looking at static elements.
到现在我们看到都是稳定的元素。
We know these are stable.
我们知道他们都是稳定的。
You wouldn't be expected to be able to guess that this would happen, because using any kind of simple theory, we would, in fact, predict that this would not be the case, but what we find experimentally is that it's more stable to have half filled d orbital than to have a 4 s 2, and a 3 d 4.
你们不用预期有能力,猜出这个会发生,因为使用任一种简单的理论,我们事实上可以预测不会是那种情况,但是我们在实验中发现的,是半填充d轨道比,4s23d4更加稳定。
