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

能还有一个我们看不到的更低的能态。

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

所以第一个电子想要最低能态。

And so it will go to the next energy state.

因此它下一个能量状态。

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

两个电子以适合第一个能量状态，或者第一个子轨道，或者第一个壳层。

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

所以你能会说，哦，最低能量状态是我刚刚画的这个洋红色内球。

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， 它们处于最低能量状态，从正到负，形成一种液晶。

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

假设我以在这里第二个立方体置于低能量状态。

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

所以我必须第三个立方体置于下一个最高能量状态。

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

然后前两个，或处于最低能态的电子，是 1s2。

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

在其他应用中，它允许通过操纵电子内的能量状态来改变单个原子的结构和性质。

In atomic clocks, the electrons around an atom's nucleus are jolted into a higher energy state by incoming radiation of a specific frequency.

在原子钟中，原子核周围的电子受到特定频率的射辐射而更高的能态。

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，当它们远离高能态时， 库仑力会变弱， 对吗？

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， 如果一个分子要通过形成双键处于最低能量状态，它有一个很好的简单解决方案。

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，至少在我的大脑中有用，以概念化能量状态的概念。

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

它能会留在那里，或者能只想回到较低的能量状态。

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

然后我们在上一个视频中说，好吧，电子从最低能态到高能态填满了轨道。

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；电子以处于一个更高的能量状态，在一个更高的台阶上，然后在它们跳下来时释放能量。

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， 分子总是向较低的能量状态移动， 而这正是它们会做的。

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能量状态，并且极其容易向更稳定的低能量状态转变，这就意味着在这个过程中它们会释放大量封存的能量。

You can barely see it there, but it's a sphere around the nucleus, and that's the lowest energy state that an electron can be in.

你在那里几乎看不到它，但它是一个围绕原子核的球体，这是电子以处于的最低能量状态。
