Here is a picture of my chart/table.

Here is a picture of what we did in class!
Here is a picture of my element, Snakium!

Questions
1 and 2 are on my table.
3 This is taken as an average and divided.
4 Many of the ones that I found were very similar. The only major difference I saw was that one group only had 57 pieces. (I think they ate most of theirs!)
5 They are taken as the average of the isotopes.
6 Most elements have isotopes, but not all of them. They range to 3 to 36 isotopes.
7 Some people ate the snacks which led to an error. This led to a difference of the isotopes. Next time, let’s hope our classmates try to stay on task and eat during their break.
