Half Lives

Today we learned about half lives and how they work. I thought that actually half of the atom was just decaying, but its only the amount of time it takes for the atoms to decay into stability, so there is no loss of mass. To help show this concept, we began to work on a half live lab. In the lab you cut out 567 squares then put them in a cup, dump the squares, and any that are on the colored side have "decayed" and are removed.

Beanium Lab

A few days ago in class we did a lab, this labs point was to show that atoms can have different masses in the form of isotopes, and it was supposed to teach us the atomic mass average formula. The formula is [(Mass)(Percent)]+[(Mass)(Percent)] for as many different isotopes as you have.

Atomic Structure and Radioactivity #2

We just learned about alpha, beta, and gamma radiation, I'm really confused.

I just found this table and it helps me a lot, I also googled some information about them and I now get that alpha particle radiation makes 2 protons lost from the atom and an overall 4 change in mass. Beta particle radiation make the proton count of the atom increase by one, and finally gamma rays don't change anything.  

Atomic Structure and Radioactivity Pre-test Reflection

So I just took the pre-test for unit 2 and I didn't know anything on there, I remembered a little about radioactive half lives but not much. I am excited but nervous about this unit, I don't think it will be easy but I also don't want it to be so hard to the point where I don't get it.

Nomenclature Reflection #2

I really understand nomenclature now I feel, I have done well on the past few tests and I think I finally get it. I lost my mastery on one section of nomenclature, however I regained it so I think it was just a mess up on my part and got the questions wrong. I am excited and ready for the next unit.

Nomenclature Reflection #1

At the beginning of this unit I was very confused and worried, I had taken a chemistry class in 8th grade and did horribly in it, so starting this I was prepared fir the worst. Then after about the first week I knew what I needed to and was doing very well on the tests, I'm not sure if it was just the teacher back then or I just get it now but I'm doing very well!
