And so the energy is zero because the electron is no longer bound. It is free.

所以这个系统能量为0，因为，电子不再受束缚了，它自由了。

So we can think about what is our most loosely-bound electron, what's that highest energy orbital, and it's going to be the 2 p orbital, that's going to be what's highest in energy.

我们来想一想,它“束缚得最松“的电子是哪一个，能量最高的轨道是哪一个？,它就是，2，p，轨道，是能量最高的轨道。

For the electron mediator, the researchers use organic molecules bound to cobalt atoms, which can switch between two states by the gain or loss of an electron.

对于电子介质，研究者们使用了钴原子，他可以在得到和失去电子两种状态之间转换。

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。

And the thing about what Schrodinger did was all he imposed on a system was the electron behaves as a wave and is bound.

薛定谔所做的,是建立在一个系统之上,电子是像波一样运动的并且是有界限的。

If a gas has bound to the the nanotubes it will impede the electron flow, altering the current.
