Atomic structure and radio activity post 11

These are some cool links that really helped me during this unit to just go over everything and tie it all together!

Alpha Beta Gama decay
half lives
Daltons atomic theory
proton neutron and electron count
mass percentage abundance formula
decay and half life

Atomic structure and radioactivity post 8

Today we learned about half-lives and i finally learned that in half lives nothing disappears the half life represents the part that is still radioactive, but nothing actually goes away like I originally thought. This is the picture of us in lab today. We cut up lots of pieces of paper and dumped them out. The ones landing on colored side were the ones that were radioactive. The white ones were the decayed ones. We continued this process multiple times.

This is a picture of a lab we did in class. We learned about radioactivity. We cut up lots of squares of paper one side was colored and one was white. When we shook them up and dumped them out, the yellow represented the ones tht decayed. It was very fun and really helped me understand half life. the only draw back was having to cut out all those squares. it took forever!

well..... that was an interesting test. I felt like i knew all the alpha gama abd beta decays. The graphs were very easy and so was the nomenclature. I found out i really struggle with half lifes and i definatly need to study that for next time.

Some fun lab pictures! The calculator for caculations the scale for mass and the beanium!

Atomic structure and radioactivity post 6

I actually understand everything i am doing in chemistry right now. I enjoy the the math part of the lessons we are doing and i think its relativley easy. I am excited for the lab tomorrow and cant wait ti pass this pre lab quiz.

I think the test went pretty well. It was easier then i thought it would be. I studied my notes and the lab questions really tied everything together. I think  I finally understand why we did the lab with the circles was because we were demonstrating rutherfords theory of bouncing thing off to find the nucleus. #yay learning :)

Atomic Stucture and radioactivity post 4

I passed my pre-lab quiz today which I was extremly nervous about, and after a day in lab I understand the way the formula works and how to work out these types of problems! I also now know was an isotope is for the first time ever and ive never really known. I enjoyed this lab and had lots of fun with the calculations, i am anxious to see what else this unit has instore. I am rather nervous for the quiz tomorrow not for the math but for knowing the different theories. I am studying tonight.

I am feeling rather stressed after today's lesson. Lots of knowledge i need to study up on. But i think it will be fairly easy after i memorize it, and i had lots of fun doing the class paper and walking around in class and talking to everyone.

Atomic Structure and Radioactivity 2

I am very excited to see what this unit has in store because I really enjoyed the lab yesterday. I wasn't very good at the lab but I really enjoyed the lab. I am anxious to see how the lab ties into our unit and what it has to do with Atomic Structure and Radioactivity. I am also very excited to go out with the class and look through the telescope to see outerspace! I look at stars a lot and I am excited to actually be able to identify things in the sky after this unit.

Automic structure and radioactivity 1

I am very excited and nervous for this unit. I didnt know almost anything on the pre-test so i definatly have a lot of ground to learn, but I enjoy math  so the work with graphs and calculators seems fun.
