Chemistry 1-31-13 Noble Gas Notation Homework

CHEMISTRY – Happy extra long weekend! We missed a bunch of you today! Hope it was a great Grandparent’s Day program.

Here’s the review we did today of a few of the noble gas notation homework problems. Are you catching on? Help session? How about next Tuesday morning, 7:15ish A.M.? Sure!

UPDATE: Now with sound!!

Chemistry 1-30-13 Noble Gas Notation

CHEMISTRY – You too can conquer electron configuration! If you caught on to noble gas notation today, great! If you are having a bit of difficulty with noble gas notation, this vodcast has a little more explanation that will be very help for you! It would also be great review for the test!

Hey, how’d you like reading electron configuration from the periodic table? Super cool, huh? And isn’t God awesome!?!

King of the Hill Competition 2013

PHYSICS: Terrific job on the King of the Hill competition!!! I’m really proud of the work that all of you did on your cars.

It was a fierce, head to head battle of the “Wills” with car parts flying all over the track, but at last the strongest car emerged victorious! Congratulations, Wil, on being King of the Hill! Also, congrats to Kever and Wil for winning the distance and speed races!

Chemistry 1-29-13 Quantum Numbers & Electron Configuration

CHEMISTRY: Wow, you did a great job today! Thank you for being so patient with my hoarse voice! Are quantum numbers making more sense now that you are actually using them? Good work today on orbital notation and electron configuration notation. I think you’re going to be seeing arrows and numbers in your sleep!

Homework update – both Monday night’s (if you didn’t finish it in class today) and Tuesday night’s homework are due tomorrow. They should be two separate assignments. And don’t forget to use the Aufbau “chart” that you learned to draw!!Also, if you want to get a head start on the periodic table drawing, the instructions are on the website. If you need another copy of the blank periodic table, it’s on the website also. Just make sure you print it on white card stock and then cut it in half.

Stay well!! πŸ™‚

Chemistry 1-28-13 Quantum Numbers

CHEMISTRY: How’re you doing? Confused yet? Don’t worry – today you learned all the background information about quantum numbers, tomorrow we’ll put it all together and it will begin to make sense. If you didn’t hear the lecture today you missed my croaking voice, but here’s an old vodcast from last year – for sure one that you want to watch!

We didn’t get to orbital notation in class today, but don’t worry, we’ll go over that first thing in class tomorrow before I take up homework! Go ahead, give it a try and see if you can figure it out!

Hon Chemistry 1-28-13 Chapter 5 Overview

HON CHEMISTRY: God bless you as you study for your test on chapter 5! Thanks for being so patient with your sickly chemistry teacher! Here’s the very last of the new info you need for the test tomorrow on electronegativity. This is an old lecture, so you may want to fast forward to the electronegativity part, or you could use all of it to review! And don’t forget Linus Pauling! (P. S. I’ll post the actual lecture from today if I can get it to upload!)

Speaking of studying for the test, did you find the Chapter 5 Stuff to Know Sheet on Edline? A couple of other items for discussion – besides the ones on the sheet, that is, why is grass greener after a lightening storm? And don’t forget about arsenic poisoning – the symptoms, the test, and how the test works.

One last thing, don’t forget that in addition to chapter 5, this test will also have orbital notation, electron configuration notation, and noble gas notation. If you need any extra practice – helps session tomorrow morning at 7:15ish A.M. Good luck studying. I’ll be praying for you!!

Chemistry 1-25-13 Quantum Model of the Atom

CHEMISTRY: So which are they? Are electrons particles or are they waves? Here’s the lecture from Friday. If you’re still having questions, you will not only want to watch this vodcast again, but also you might watch this video clip that we saw in class today on Quantum Mechanics, and also the one from yesterday – Animated Quantum Mechanics.

By the way, speaking of Quantum Mechanics, did you read the cartoon? πŸ™‚

Chemistry 1-24-13 Flame Test Lab

CHEMISTRY: Wow! Great job on the flame test lab – pretty cool, huh?! It’s one of my favorite labs. What was your favorite color. Did it help you understand something about how fireworks must work?

Lab reports are due TOMORROW. What about the conclusion? Answer the objective, and explain how you used flame tests to identify an unknown. And don’t forget the questions at the end!
