Hon Chemistry 3-2-18 Molecular Geometry Homework & cLAB

HON CHEMISTRY: Happy Friday!!! It has been one looooooong week!!! We missed you guys who were absent today! Below is a look at the molecular geometry homework we went over today (yes, I said today – we have a somewhat working mic!!).

Also we began the cLAB: 3D molecules today in class, and this vodcast will give you a head start on that assignment. Be sure and read the lab sheet BEFORE you start and before you turn in the assignment!!

Have a wonderful weekend!!

Hon Chemistry 3-1-18 Molecular Geometry

HON CHEMISTRY – Who knew we’d be doing geometry in chemistry?!? Here’s the lecture on molecular geometry, with a little practice at the beginning on polyatomic ions. Molecular geometry is super easy. Make sure you know how to draw Lewis structures, then determine the type of ABE structure and you’ve got it. Easy-peazy!

For Friday – print off the cLAB: 3D Molecules, but you don’t have to pre-draw the structures ahead of time. We’ll use the laptops in class to make some molecules!

Hon Chemistry 2-28-18 Resonance & Polyatomic Ions

HON CHEMISTRY: Wow! Lewis structures, multiple bonds, and now resonance, and now polyatomic ions! That’s a lot you’ve conquered in the last couple of days!

Here’s some good advice – don’t take shortcuts. Learn the proper steps on the easier molecules, and you’ll be able to do the hard ones. And if it’s still all Greek to you, don’t worry! Keep practicing and you’ll get it, I promise!! Don’t forget to count electrons and don’t forget CONS!

Honors Chemistry 2-27-18 Lewis Structures & Multiple Bonds

HON CHEMISTRY – I just love dots! Here’s the lesson from Tuesday on drawing Lewis structures. Make sure you practice, practice, practice! Warning: before you know it, you’ll be seeing dots everywhere!

Hon Chemistry 2-26-18 Intro to Chemical Bonds & Covalent Bonding

HON CHEMISTRY: Hey guys, welcome to chemical bonds! Great job on using electronegativity to determine bond type. Make sure you add that scale and also the diatomic molecules to your “things I have to memorize for the test” list.

Hon Chemistry 2-20-18 Chapter 5 Overview

HON CHEMISTRY: Okay, this no microphone thing is getting a little old, BUT I think I’ve found a couple of old vodcasts that kind of sum of what we’ve been doing the last couple days. They won’t be be exactly like our last couple of classes, but I think they’ll be helpful. First is an overview of Chapter 5 – including the Marsh test results. Below that is an old overview of the Reverse Scavenger Hunt.

Do you plan to practice #50 – 53? Strongly encouraged! Did you understand it when we did it today in class? Help session Friday morning, 7:20ish A.M.

Hon Chemistry 2-15-18 d & f-block Intro & a Look Back at cLAB: Element Reverse Scavenger Hunt

HON CHEMISTRY: Wow! Did you every dream there was that much interesting and important stuff to know about the s, p, d, and f block elements?! Here’s the introduction to the d & f blocks, and then, our beginning of running through all the slides to clarify some information and filled in gaps you might have had.

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 (coming very soon!!)!

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

The videos that you must watch from the s-block for the test are potassium, magnesium, and calcium.

The videos you need to watch for the p-Block are carbon, nitrogen, oxygen, fluorine, and chlorine. http://periodicvideos.com/

The elements from the d block that I especially want you to watch are copper and mercury. And there are other interesting ones you might like to watch just for fun!

The videos on from the f-Block that you need to watch are: neodymium, thorium, and uranium. Go pop some popcorn and have some movie time!

Hon Chemistry 2-8-17 Electron Affinity, Ionic Radii & Electronegativity

HON CHEMISTRY: Here’s the last of the trends – not car trends, periodic trends! For now, it’s an lesson from last year, so fast forward past the syllabus part! 😉

Have you begun by watching the videos on the Periodic Table of Videos site? Great place to gather information for the cLAB!

Hon Chemistry 2-7-18 Atomic Radii & Ionization Energy

HON CHEMISTRY: Hey guys, here’s the first lecture on periodic trends – atomic radii and ionization energy. You made some great connections today!

If you’d like to get a head start on the element videos that I talked about in class today, they are at periodicvideos.com. Very interesting(!), with tons of useful information!

Hon Chemistry 2-5-18 History of the Periodic Table & cLAB: Element Reverse Scavenger Hunt

HON CHEMISTRY: Great start to a new chapter! I love that you are going to be learning to research some really cool stuff about the elements on the Periodic Table.

Here is the intro the the history of the periodic table and and your short intro to the cLAB: Element Reverse Scavenger Hunt. This doesn’t exactly match what we did in class, but it’s a good start. Begin the vodcast at 4 minutes or so. We’ll continue with some of the rest of the Periodic Table tomorrow!
