The technology has spread to many new countries and less stable countries since the end of the Cold War,".

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?
So, that also tells us that the n minus ion is less stable than the neutral atom itself.
而且,这还告诉我们,负一价的氮离子不如中性氮原子稳定。
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。
Who thinks it's more stable, show of hands? All right, who thinks it's less stable? Very good.
认为更稳定的请举手,好的,谁认为更不稳定?很好。
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。
