Test Day!

After taking the test today I am definitely glad I read the book and completed all the practice test Frankenberg offered. This unit was easier than most we have done and it was a nice break from the difficult things we have been learning. I hope every did well on there test and that the next unit is just as interesting!

Review For The Test

Here are a few links to help review for the test! I also found the practices quizzes and worksheets very helpful on Schoology!

Wavelength

Spec 20 Lab

My partner was not here to help me with the spec 20 lab so Mrs. Frankenberg was my partner. In this lab we had to test the %T and absorbance of a Chromium solution and Cobalt solution. The lab was very time consuming, but it was cool to see the results!

Wavelength and Energy

In class we learned how to calculate wavelength and frequency. The formula is rather simple: energy of light=wavelength*frequency. The speed of light is 3.0x10^8. By knowing this formula and number it was easy to calculate the wavelength or frequency when asked. Also we learned that violet has the shortest wavelength and highest frequency of all visible light.

Electron Configuration

Today we got to color in class! We did this in order to show the different sections on the periodic table. These sections include s,p,d, and f. The s sublevel holds 1 orbital and can contain 2 electrons, the p sublevel holds 3 orbitals which each orbital can contain 6 electrons, the d subshell holds 5 orbitals and can contain 10 electrons, and lastly the f subshell holds 7 orbitals and can contain 14 electrons. These different subshells help to determine an elements electron configuration which helps to locate it on the periodic table.

Flame Test Lab

We did a flame test lab in class to see what color different metals burned at. It was sometimes difficult to see the exact color of the flame the metal produced, but it was still a really cool lab. After we finished collecting data, we had to determine the wavelength these metals burned at and the moles/photon for each metal.
