Unit Test Thoughts

Well, I don't have the grade back yet... but I think I did pretty okay. I actually got to read all 50 questions, which is rare for any unit test. So I'll count that as a victory.

Periodic Trends

The last lesson for this unit was periodic trends. The periodic table has trends that can provide information about the chemical and electronegative characteristics of S & P block atoms. i believe this concept was very easy to understand as long as you memorize the details.

Electronic Structure Quiz

Overall I feel pretty confident about this unit. I don't have a ton of time to study but I'm pretty sure I know the material well. Let's hope for the best! Here's some study stuff:

Wavelength Lab

In this lab we held a spectroscopic analysis with a spectrophotometer, in order to see the wavelengths of chromate and cobalt. We adjusted various knobs on the spec 20 and found the amount of light in blue and pink solutions, which were our metals. This lab was tedious and very boring

Flame Test Lab

Today we got to play with fire. Basically we took solutions and held them in a flame to determine what color they burned. From the color we can tell wavelength, and then calculate energy. Here so pics of the awesome colors!

Electronic Structure

The next unit, Electronic Structure, This unit is more based on concepts than math, unlike our previous units. There is a lot less little variations. We learned about the wave nature of light. We also talked about wavelength, the wave spectrum, frequency, and calculating energy. Hopefully this continues to be easy.
