More Lectures

Chemical bonding revolves around one concept: a covalent bond is formed by sharing electrons. We do not focus on ionic bonding too much in this unit. Atoms want electrons to fill their valence shells to make them stable. More often than not, it's 8 electrons to fill a valence shell except for Be, B, H, & He. We learned lewis structures, formal charge, electron geometry.

Atomic Model lab

Basically this lab was about practicing have need share. I've been having a lot of struggle focusing so this stuff is still lost on me. I'm trying though

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
