 So Stephen, I should buy and I'm going to take you through how to do some electronic structure calculations on atoms in Spartan. So I've gone to this V desk interface and once I'm there, I'm going to click here on the lower right, you'll probably have to enter some credentials, which I've already done. And eventually it'll take us to this Spartan screen, which I'll double click on and it'll launch Spartan in just a moment. Now I've already set up these icons so they're ready to go. If you want to do that, you can go to preferences like this and set that up. But I'm going to go ahead and build helium and for that, I'm going to go to the inorganic menu, going to choose helium and which is there. And I'm going to choose this one stick coming off it because I'm actually going to delete even that one. And so now I have helium and we go to this, this calculations icon, which you would be able to also get through through the setup down, pop down. Now we can take all the defaults on this, so I'm just going to submit and we can save it however we want. And and it tells me that it's completed. So next what we're going to do is I'm going to choose this icon and which again is on here. It's under the display pop down and it will show you a couple of options here on the left. It's an energy ladder. I kind of like to show these orbitals in a mesh view. And I've let the model default to ball and spoke, which is fine. And there's an orbital. It's a 1S orbital and there's another orbital. It's actually the 2S orbital. So you can see the 2S is bigger than the 1S. It's got a little bit of structure inside. And after that, you do the same thing for other noble gases to begin with. I would say next you should go for neon, then argon and and and so on.
