Let's calculate the energyįor the second energy level, so E two, this would One squared, alright? Which is of course just one, and so this is negativeġ3.6 electron volts, so we already knew that one. Where N is equal to one, so whatever number you have here, you're gonna plug in here.

So the energy for theįirst energy level, right, we already know what it is,īut let's go ahead and do it so you can see how to use this equation, is equal to negative 13.6 divided by, so we're saying the energy Squared, where N is an integer, so one, two, three, and so on. Negative 13.6 electron volts, and we divide that by N Into my equation here, and so I can just rewrite it, so this means the energyĪt any energy level N is equal to E one, which is The energy associated with an electron, the lowestĮnergy level in hydrogen. And so if you do that math, you get negative 13.6 electron volts. And so, if I multiply these two together, the joules would cancel and give me electron volts as my units. So if I take negative 2.17 times 10 to the negative 18 joules, I know that for every oneĮlectron volts, right, one electron volt is equal to 1.6 times 10 to the negative 19 joules, and so I have a conversion factor here. So one electron volt is equal to 1.6 times 10 to the negative 19 joules. That into electron volts, it just makes the numbersĮasier to work with. Value for that energy to be equal to negative 2.17 times 10 to the negative 18 joules. The energy associated with an electron, and the lowest energy level of hydrogen. Not necessary to watch the previous video, you can just start with this video if you want. So in that last video, I showed you how to get this equation using a lot of Physics, and so it's actually
