There might yet be a lower energy state we don't see.

还有一我们看不到的更低的。

This happens because the atoms are falling into lower and lower energy states as they cool down.

这是因为原子在冷却时进入越来越低的量状。

So the first electron wants to go into the lowest energy state.

所以第一电子想要进入最低。

And then the first two, or the electrons in the lowest energy state, will be 1s2.

然后前两，或处于最低的电子，将是 1s2。

And two electrons can fit in that first energy state, or that first sub-orbital, or that first shell.

两电子以适合第一量状，或者第一子轨道，或者第一壳层。

And that model is actually useful, at least it's useful in my brain, to conceptualize the idea of energy states.

该模型实际上很有用，至少在我的大有用，以概念化量状的概念。

They're at their lowest energy state when they're lining up together, positive to negative, into a kind of liquid crystal.

当它们排列在一起时， 它们处于最低量状，从正到负，形成一种液晶。

And it might stay there or it might just want to go back to its lower energy state.

它会留在那里，或者只想回到较低的量状。

So you might say, oh, the lowest energy state is this magenta inner sphere that I just drew.

所以你会说，哦，最低量状是我刚刚画的这洋红色内球。

And so it will go to the next energy state.

因此它将进入下一量状。

So I have to put the third cube at the next highest energy state.

所以我必须将第三立方体置于下一最高量状。

Among other applications, it allows the structure and properties of individual atoms to be altered via the manipulation of energy states within electrons.

在其他应用，它允许通过操纵电子内的量状来改变单原子的结构和性质。

Well, if a molecule is going to be at its lowest energy state by forming a double bond, it has a nice simple solution.

好吧， 如果一分子要通过形成双键处于最低量状，它有一很好的简单解决方案。

And let's say I could put the second cube at a low energy state here.

假设我以在这里将第二立方体置于低量状。

The opposite is true as well; electrons can be in a higher energy state, up on a higher step, and then give off energy when they jump down.

反之亦然；电子以处于一更高的量状，在一更高的台阶上，然后在它们跳下来时释放量。

Or in the case of electrons, when they get further away from a high energy state, the coulomb force is weaker, right?

或者就电子而言，当它们远离高时， 库仑力会变弱， 对吗？

So when it goes back to its lower energy state, it would emit the photon back, and that's actually why you see some things sometimes glow.

所以当它回到较低的量状时，它会发射回光子， 这就是为什么你有时会看到一些东西发光的原因。

Just like a ball at the top of a hill, the molecules always move towards a lower energy state if they can, and that's just what they'll do.

就像山顶上的球一样，如果以的话， 分子总是向较低的量状移动， 而这正是它们会做的。

And then we, in the last video, we said, OK, the electrons fill up the orbitals from lowest energy state to high energy state.

然后我们在上一视频说，好吧，电子从最低到高填满了轨道。

Instead, they're stuck in a loosely bound high-energy state and are dying to move to a more stable lower energy state, which means releasing a lot of pent-up energy in the process.

相反，它们处于一种松散约束的高量状，并且极其容易向更稳定的低量状转变，这就意味着在这过程它们会释放大量封存的量。
