Chemistry 3-29-21 Intro to Atomic Theory

CHEMISTRY: Here’s the last of our discussion of Dalton’s atomic theory vs. the modern atomic theory. If you weren’t in class today, be sure and get the definitions and applications of allotropes and isotopes. I still say it’s pretty cool that something that was discovered so long ago is something that we use today!

Now on to checking out part of those theories! Today we did Part 1 of the Conservation of Mass lab. If you weren’t in class, you’ll need to make up Part 1 before we do Part 2 in class on Wednesday. You can make it up tomorrow, Tuesday, 5th or 7th periods, or you can come Wednesday morning before school at 7:50 A.M. It will take about 15 minutes. Be sure and read Part 1 of the lab so it will go faster!

Hon Chemistry 3-29-21 Quantum Numbers & Intro to Orbital Notation

HON CHEMISTRY: Great job with quantum numbers today! And then on to orbital notation! Wow, it was a lot. Confused yet?

Don’t worry! Today you learned all the background information about quantum numbers. Did it start to make more sense when we put it all together with orbital notation? Let’s take it up again tomorrow!
