If you look on the Periodic Table this is 598 atomic hydrogen. And, sure enough, there is 13.598, which is this number here in electron volts.
如果你查找元素周期表上的氢原子,毫无疑问,它的电离能就是13。,这个数值也是电子伏的值。
And let's look at the final kinetic energy that we'd observe in this spectrum, which is 384 electron volts, so what is that third corresponding ionization energy?
