So that means that the more stable molecule is going to be this molecule here, which actually puts the negative charge on be more electronegative atom.
因此这意味着更稳定的分子,应该是这一个,它真正把负的电荷放到了,电负性更高的原子上。
And you would expect that that would be a much stabler compound because, instead of plus one attracting plus one, now you have plus two attracting minus two.
可以预见,这将会是更稳定的化合物,因为不再是一价正离子吸引一价负离子,而是二价正离子吸引二价负离子。

Also, when we're looking at the Schrodinger equation, it allows us to explain a stable hydrogen atom, which is something that classical mechanics did not allow us to do.
当我们看一个薛定谔方程的时候,它给出一个稳定的氢原子,这是在经典力学中做不到的。
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。
So, what we know is happening is that were having transitions from some excited states to a more relaxed lower, more stable state in the hydrogen atom.
我们知道,这里所发生的是,氢原子从激发态到更低更稳定的态的跃迁,而我们用眼睛可以探测到的。
But I want you to tell me in terms of thinking about formal charge, which Lewis structure would you predict to be the most stable?
但我想让大家告诉我,从形式电荷的角度考虑,你会预测哪一个路易斯结构是最稳定的?
So it turns out it is, in fact, more stable.
结果应该是更稳定。
It just doesn't have any risk to it, it has no variability.
公债是没有风险的,是稳定的资产。
And we haven't talked about reactions at all yet, so you don't need to worry about the specifics of that exactly, but just that if you have this negative change in energy, you have a more stable product than you do reactant.
当然我们还没有开始讨论反应,所以你不用担心它的细节是怎么样的,你只需要知道,如果能量的变化是负值,那么你将得到一个比反应物更稳定的生成物。
Well what it means is that starting in the 1930s we began to think of central banks as managing the money stock to stabilize the economy.
好吧,它意味着从二十世纪三十年代开始,我们就认为中央银行是,为了稳定经济而,管理金融债券的。
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。
And there are various forces that play in the nucleus that will dictate when this will be stable and when it won't be.They isolated it, but it decays very quickly on the order of microseconds Lifetime on the order of microseconds.
在原子核中有很多种力,都会产生作用,当条件是稳定的,还有当它不是的时候,它们提取出来,但是它会以微秒的速度衰变,生命只有几微秒长。
CO2 is really a stable molecule.
二氧化碳的确是稳定的分子。
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。
This is good, dilithium is stable.
这很好,双锂是稳定的。
Part of the reason why I'm endorsing this market stability regulator is that there's no way we can set up a system that is both very effective in allocating resources and that is also very stable.
我赞成市场稳定性监控者,的部分原因是,没有方法建立一个,既能完全有效配置资源有非常稳定,的系统。
They have risks that their overhead won't cover their risk is that a steady stream of people won't come and be making a steady stream of bets at which each of them has a slightly negative expectation.
他们的风险是能否支付管理费用,他们的风险是不再有稳定的客流来消费,同时每一个人都怀着一丝消极的期待,下源源不断的赌注。
So it helps us predict, will we see this, for example, h 2, which we're going to be about to do, we'll see is stabilized because it has more bonding than anti-bonding.
这帮助我们预测,我们等会会看到,比如H2O,我们等会要讲到,我们会看到它更稳定是,因为成键比反键更多。
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.
