OK, elements with low average valence electron energy, and here I'm saying below 11 electron volts, these are good electron donors.
平均价电子能都较低的元素,我是指那些低于11电子伏的,这些是很好的电子给体。
Its average valence electron energy is 5.2 electron volts, which is a heck of a lot less than 11.
它的平均价电子能是,5。2电子伏,那比11电子伏要少得多。
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?
然后让我们来看一下,在光谱中观测到的,最后一种动能,它大小是,384,电子伏,那么这相应的第三种电离能是多大?
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。
These are photodetectors, band gap two electron volts, respond to visible light.
这是光电探测器,能带隙为2电子伏,当它反应于可见光。
If you multiply entry 23, which is 13.6 electron volts I will show you what the electron volt is in a few minutes. We will just put it up here prematurely. But that is given in your chart.
如果乘上第23个常量,代表13。6电子伏,接下来我就会向你们说明什么是电子伏,我们先提前把它提出来,但那只是放在你们的图表中。
And it turns out that the first kinetic energy that we would see or the highest kinetic energy, would be 12 32 electron volts.
结果是我们最先观测到的动能,也就是最大的动能,将是,1232,电子伏,那。
And then the conversion of joules to electron volts is entry 42. If you multiply those two together you will end up with this quantity.
然后焦耳和电子伏的转换,是在第42个常量,如果你把这两个放一起,你将得到这个数值。
I couldn't quite hear, but I have a feeling everyone said 870 electron volts.
虽然我听不太清,但是我感觉大家回答的都是,870,电子伏。
0eV This is almost 20 eV, high average valence electron energy, greater than 13 electron volts.
它的价电子能是,这是很高的价电子能,比13电子伏要高。
Good, quick math. All right, so 48 electron volts.
很好,算得真快,48,电子伏。
