So if we have a negative change in energy for any reaction as it's written, what that actually means is we're giving off energy as the reaction proceeds.

如果我们像这里写的这样,在任何一个反应过后，得，到的能量变化为负值,这就意味着我们在这个过程中放出了能量。

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？

this happens spontaneously, you actually get energy out of the reaction as this happens.

这是自发的，当反应发生的时候,你会自发地放出能量。

So that's why we're giving off extra energy.

这也就是我们放出多余能量的原因。
