Chemistry Notes from cLAB: Element Reverse Scavenger Hunt

CHEMISTRY: Have you missed any of the discussion from the intro to each block in the Element Scavenger Hunt? This vodcast is for you!

Test Monday(!) and I’m going to let you use your Scavenger Hunt on the LAST ten minutes of the test (!) – so I thought I’d post TWO VERY IMPORTANT vodcasts to help you study for this part of the test. First is the beginning again – a history of the periodic table and the general notes on each block – some of this you may have seen before. Second vodcast is a final run through of slides – clarifying some information and filling in gaps you might have.

Amazing! Before you started the cLAB, did you every dream there was that much interesting and important stuff to know about the s, p, d, and f block elements?!

As you are studying, make sure you go back and practice figuring out the period, block, group, and type of element from the electron configuration. And don’t forget the topics I asked you to research for yourself that you will find on the Chapter 5 Stuff to Know Sheet on Edline!!

To make your research even more interesting(!), there are some really interesting videos with tons of useful information at this site:

Some great videos to watch from the s-block for the test are potassium, magnesium, and calcium.

Some great videos to watch for the p-Block are carbon, nitrogen, oxygen, fluorine, and chlorine.

Some great videos to watch from the d block are: copper and mercury. And there are other interesting ones you might like to watch just for fun!

Some great videos to watch from the f block are: neodymium, thorium, and uranium. Go pop some popcorn and have some movie time!

Hon Chemistry 2-3-15 Conclusion of cLAB: Element Reverse Scavenger Hunt from Tammy Skinner on Vimeo.

Chemistry 3-29-19 Chapter 5 Overview

CHEMISTRY: Awesome review today! Here is our overview of the test from today. Lot’s of great practice! Here are links to the videos we watched today on arsenic and the Marsh test. Can you draw and describe the test for arsenic? Marsh Test for Arsenic AND Napoleon’s Wallpaper

Speaking of studying for the test, are you practicing the things we talked about with recent homework? And are you using the Chapter 5 Stuff to Know Sheet?

God bless you as you study! I’ll be praying for you!!

Chemistry 3-29-19 One Last Look at the Second Part of Chapter 5

CHEMISTRY: Here is a super important look at some of the homework questions from last night – and others! If you were absent from class today, it would be a GREAT idea for you to closely watch this vodcast and play along! It would be great help for the test!

Speaking of studying for the test, did you find the Chapter 5 Stuff to Know Sheet? Have you made your own? Also, have you checked out the review games that are in the online textbook? Great way to practice answering questions!

God bless you as you study! I’m praying for you!!

Chemistry 3-28-19 Electron Affinity, Ionic Radii & Electronegativity

CHEMISTRY: So you’re saying, not only are there atoms that want to get rid of electrons, there are atoms that want to take them? Here’s a picture of chlorine taking an electron from sodium – or sodium giving an electron to chlorine. I’ll let you decide!

Hon Chemistry 3-25-19 Ionic vs. Covalent Bonds, Pt. 2 & Metallic Bonds

HON CHEMISTRY: Molten iron, wow! Here’s the lecture on the rest of the notes on ionic vs. covalent bonding, followed by metallic bonding.

Aren’t you glad there are no structures to draw for metallic bonds?! Make sure you can use the electron sea model to explain the properties of metals. Also be able to compare and contrast all three types of bonds.

Have you made your own Chapter 6 “Stuff to Know Sheet”? Great way to get organized as you get ready for this test!!

Hon Chemistry 2-22-19 Ionic Bonding

HON CHEMISTRY: Hey guys, here’s the lecture on a different way that atoms come together – ionic bonding.

Keep in mind that when you write ionic bonding, you’re not trying to arrange a single structure like you do with Lewis structures. Instead, you’re writing an equation that shows electrons being lost by one atom and gained by another atom. And make sure you put the dots in the right order!

Also important, pay close attention to the comparisons of ionic and covalent bonds – and WHY! And whatever you do, stay away from bubble baths if you have mortal enemies!


Hon Chemistry 3-19-19 Dipoles

HON CHEMISTRY – So why is molecular geometry important? What’s the big deal about knowing the correct shape of molecules? Here’s the beginning of the answer! Great discussion today and great job on drawing dipoles. We’ll continue with intermolecular forces tomorrow.
