Beanium Lab

Beanium Lab
Today in class we did a "Beanium Lab" pretending that beans were a new element looking at the different isotopes. We uses white, black, red, and pinto beans for this "experiment". We found that in our sample of Beanium, we had 18 white isotopes, 12 black, 10 red, and 13 pinto, for a total of 53 isotopes. We discovered that the total mass of the white beanium was 5.45 grams, black was 2.36 grams, red was 3.43 grams, and pinto was 4.20 grams. The average mass of the isotope was .303 g white, 0.197 g black, 0.343 g red, and 0.323 g pinto. We also calculated the abundance of each isotope, with white being 33.96%, black being 22.64%, red being 18.87%, and pinto 24.53% abundance. Using the average mass of each isotope, the atomic mass formula, and the % abundance, to end this experiment, we calculated the atomic mass, which ended up being roughly 0.291 grams.

Day 1 of Atomic Structure

Atomic Structure
Yesterday, we learned about Dalton's Atomic Theory, and that not all of his theory is still true today. We practiced calculating the percent composition, also known as the proportion of mass. Thomson used a cathode ray tube in order to show atoms of any element emit particles with a negative charge. We learned about Rutherford and his gold foil, he gave us the proton. The current Atomic Model is a "cloud model", meaning that there are no distinctive boundaries.

Atomic Structure and Radioactivity Pretest...

     We recently took the Atomic Structure and Radioactivity Unit Pretest. It was difficult because I do not yet understand any of the fusing, fission, bonding, etc rules. Although we touched on half-lives way back when in physical science, I think I did alright on some of those questions. I still need a refresher before a final grade. Can't wait to learn more about this unit, it will be a good one!

Final, Final Thoughts about Nomenclature...

     Finally, the information sticking with me is all about ionic compounds. I learned how to name them, even with roman numerals. We learned that cations are metals, and anions are nonmetals.

Final Thoughts on Nomenclature...

     In the Nomenclature unit, the best thing that I did was the Frontier Chemistry Project. I'm in the woods and prairies a lot (truthfully) for running and hiking. I think that if I ever encountered some type of plant, I may be able to use it to my benefit, in case of an emergency. I've been very confident in identifying plants when I see them, and they can now be of help. This project not only helped me understand HOW the plants could help, but also WHY they'll help chemically.
