Well this lab was pretty fun, but i'm glad i wasn't Lee having to count all of those little plastic things. Our purpose of this lab was to attempt to concretize the ideas of quantum mechanics, orbitals, and probability models. We were supposed to have 40 ml of the plastic split pea things, but that would have way too many to count so we just narrowed it down to 20 ml. We had a funnel to put the peas in to drop down on to the target. We also had a paper target that had 6 different circles.
We first started with a high energy. We held the bottom of the funnel closed and put the plastic spit peas in the funnel. We then let the bottom of it open and some started to fall out, but we had to use either our finger or a pencil to make the rest of them come out. When they all fell we counted them and wrote how many had fallen in each circle and then wrote them down in our data table. After we did that we picked them all back up, put them in the cup and changed it to a lower energy. We then repeated it but putting them back in the funnel and so on... After we wrote down the information for that, we compared the data and the peas from the lower energy were all bunched together in the first couple rings of the target. This is because they fell from a lower height so they stayed closer together, instead of falling from a higher height and spreading out, and going everywhere when they fell.
Electron configuration isn't a hard thing to get once you get the hang of it. At first i thought to myself and was like what is this? I didn't get it at all first, and i'm still a little confused about it, but i'm getting better now. If you look at a Periodic table of elements it's way eaiser to help you figure things out.
Here is a little example of a chart that Mr. Ludwig taught us to help us out: The numbers in the parenthesis are supposed to be exponets, but since i can't, i'll just be in parenthesis.
1s(2)
2s(2) 2p(6)
3s(2) 3p(6) 3d(10)
4s(2) 4p(6) 4d(10) 4f(14)
Here is an even better chart of it!:
S's can have up to 2 electrons per orbital, P's can have up to 6 electrons per orbital, D's can have up to 10 electrons per orbital, and F's can have up to 14 electrons per orbital.
