Chemistry 2-21-18 Electron Configuration Review

CHEMISTRY: Kind of an odd Wednesday! A mix of homework review and new notes – all super important stuff. I loved watching the way you were applying what you know about electron configurations!! This vodcast from last year is definitely one you want to watch if you’ve been absent and one that would be helpful to look back at as you study for the test! Start watching it at 4:00 minutes.

Need more help/practice? Help session next MONDAY morning, 7:20ish A.M.

Chemistry 2-20-18 Noble Gas Notation

CHEMISTRY – You too can conquer electron configuration! If you caught on to noble gas notation today, that’s great! But if you are having a bit of difficulty with noble gas notation, no problem! Watch this vodcast again and it will make even more sense the second time! 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!?!

Chemistry 2-15-18 Orbital Notation & Electron Configuration Notation

CHEMISTRY: Wow, you did a great job today! Did quantum numbers begin making more sense when you started using them? Good work today on orbital notation. I think you’re going to be seeing arrows and numbers in your sleep!

Then, just when you were getting the hang of drawing arrows, I go and change it! But don’t you think writing electron configuration notation is a whole lot shorter than doing orbital notation? Don’t get me wrong, knowing how to do orbital is great for seeing how the electrons are paired, but this way is waaaay shorter!

Be sure and practice with the homework tonight, and don’t forget to use the Aufbau “chart”!!!!

Need extra practice or help with this chapter? Ask me about a help session next week!

Chemistry 2-14-18 Quantum Numbers

CHEMISTRY: See what Bohr and Heisenberg’s work led to? Now you have the tools you need to determine where electrons are in an atom – but can you?!?

Here’s the vodcast from today on quantum numbers and the rules you’ll use to use them. Be sure and practice drawing the Aufbau Chart!! The good news – quantum numbers will begin making more sense when you started using them!

Chemistry 2-12-18 Bohr Model & Quantum Model of the Atom

CHEMISTRY: So which are they? Are electrons particles or are they waves? Here’s the lecture for Monday. If you’re still having questions, you will not only want to watch this vodcast again, but also you might watch these video clips that we saw in class today – The Emission Spectrum of Hydrogen, and also this one Animated Quantum Mechanics.

Tomorrow is the Emission Spectra of Atoms lab! Don’t forget to print the lab and read it BEFORE you come to class!

Chemistry 2-8-18 Photoelectric Effect & Wave Problems

CHEMISTRY: Fun field trip today!! Good job coming up with examples of the photoelectric effect. What? There really aren’t tiny people living in boxes above the doors at Wal-mart? And I just thought of another one, what about those automatic flush toilets!

What did you think about the energy problems? Again, make sure you not only memorize formulas, but also be careful to learn the symbols and units for each of the quantities you’re going to use, it’s easy to get them confused!

Need practice? What about a help session?

Chemistry 2-6-18 Wave Properties of Light

CHEMISTRY: So tell me again, if we’re supposed to be figuring out electrons, why are we studying waves? Here’s the lecture from Tuesday on that very thing!

Make sure you know the types of electromagnetic radiation and the uses of most of them (all except for long waves). And just in case you really need to sing that song again, here’s The Electromagnetic Spectrum Song

How did you like the light problem formulas – so far? We’ll explore wave problems further tomorrow – be sure to bring a calculator to class!

Chemistry 2-5-18 Spectroscopy Lab

CHEMISTRY: How’d you like playing with light? Kind of pretty, huh?

Are you clear on how to turn in the lab report? Observations from the diffraction grating today will be in two parts: 1) the written observation – answers to those four questions for BOTH types of light on notebook paper, and 2) your drawings of both kinds of light on different half sheets of card stock or heavy white paper, and then both drawings mounted together on one side of a single sheet of construction paper. Be sure to label with the type of light!

Observations from Part 2 with the spectroscope will be answered on the actual lab sheets/packet. Be sure and read ahead so that you can double check to make sure you answered every single observation and question. The entire packet will be due on Monday!!

Chemistry 1-30-18 Applications of Radioactivity, Pt. 2 and Fission & Fusion

CHEMISTRY: Hey guys! Here’s the laaaaast part of the charter – fission and fusion. Have you started studying? Be careful and don’t take the test for granted! And don’t forget to check out the the Chapter 21 Stuff to Know & sheet.

Make sure you keep practicing half-life problems and nuclear equations. Also, make sure you’ve memorize the nuclear symbols for alpha particles, beta particles, positrons, neutrons, and protons. And then there are tons of notes on the conceptual stuff. Properties of radioactivity, people, types of radioactive decay, applications of radioactivity, definitions, definitions, and definitions!

Help session Thursday morning, 7:20ish A.M.

Chemistry 1-25-18 Applications of Radioactivity

CHEMISTRY: Radioactive isotopes all around! Did you ever dream there were so many applications of radioactivity? Thanks for the great job on adding to the lecture! This is a pic of a test used to check on blood flow through the heart during a stress test. Fun, huh!? Click on the link below the pic to learn more from Cedars-Sinai hospital.

Here’s the lecture from today – applications of radioactive isotopes. We’ll finish more applications and then fission and fusion on Monday. Have you checked out the Chapter 21 Stuff to Know & Study Suggestions sheet? Check out the Test Info tab!

IMPORTANT: Don’t forget about the Half Life lab! Data is due when? Where? check the syllabus for info!
