What is the binding energy of the ground state electron in hydrogen?

氢在基态的情况下，它的电子结合能是多少？

Now, if this incident energy is great enough it will take an electron out of the ground state and promote it.

现在，如果入射能足够的话，它会将一个电子从基态中释放出来，并且加速它。

youdao

The extra electron fills up the lower-energy state in the conduction band, causing excited electrons to, effectively, spill over into the higher-energy, photon-emitting state.

这个额外的电子填充了传导带的较低能级，有效的导致了被激发的电子溢入较高，释放光子的能级。

youdao

When a light particle,or photon, hits an electron, the electron jumps to a higher energy state.

So if we think about, for example, this red line here, which energy state or which principle quantum number do you think that our electron started in?

我们来看看，比如这里的这个红线，它是从主量子数,等于多少的能级发出的？
