An unstable atom gives off its excess energy until it becomes stable.

不稳定的原子释放出多余的能量，直到变得稳定。

An unstable atom gives off its excess energy until it becomes stable. The energy emitted is radiation.

不稳定原子在达到稳定状态前，需要释放出自身多余的能量，这一能量即辐射。

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？

youdao

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。

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。

So, basically any time we have a really high positive number of electron affinity, it means that that atom or ion really wants to gain another electron, and it will be very stable and happy if it does so.

因此，基本上无论什么时候,只要我们有一个很大的正的电子亲和能，这就意味着这个原子,或离子非常希望得到一个电子，如果它得到了，会变得更稳定更开心。
