Helpful Links for Test!

While I was studying for the test tomorrow I found a couple of online resources that helped me fully grasp some of the ideas of the Unit! They are listed below.

Half Life
Radioactive Decays

Hope they help you guys!

Forensic Archaeology Lab

Today in class we made excel graphs depicting how radioactive elements decay over time. The entire lab was an overview of half-lives. We cut up 567 tiny paper squares and pretended that they were atoms. We jumbled them up and poured the out and the papers that had the colored side faced up were considered to be a decayed atom! We would remove them and redo the process! It was a very tedious lab, although it did help me get a full understanding of half-lives!

Heres a link that helped me undestand!  http://hyperphysics.phy-astr.gsu.edu/hbase/nuclear/halfli.html

Beanium Lab

The Beanium Lab was made to help us realize that not all atoms are the exact same for each element. There are many different types of Isotopes for each element. We essentially counted out different beans and used them as examples of different isotopes and got different masses for each bean.

We were able to calculate the average atomic mass for the element "Beanium" by using the Atomic Mass Formula.

Atomic Structure and Radioactivity Quiz #1

I didn't think the quiz was very hard, a lot of it was memorization. Not much application besides a few of the math problems. Good start to this new chapter!

Heres a hands on activity that reviews how to calculate average atomic masses! http://algebralab.org/practice/practice.aspx?file=Algebra_AverageAtomicMass.xml

Radioactivity Pre-Test

It was an interesting test. I recognized a lot of words but I didn't know how to do the actual problems. I remember learning about a lot of that stuff in physical science but that was a while ago and I do not remember it enough!

Here is a resource that helped me refresh on Alpha Particles: http://www.physics.isu.edu/radinf/alpha.htm

How I felt about the Nomenclature Test

I personally did not think the test was terribly hard. I did get tripped up on the Type 3 a little more than anything. It also did get sticky when I needed to remember the charges of the poly-atomic ions and I blanked a couple times.

How I feel about Nomenclature

Nomenclature was always intimidating before I was actually introduced to it. Before I started chemistry it all looked like a bunch of gibberish. After I started learning how things are named it started to make a lot more sense.
