CHEMISTRY: Radioactive isotopes all around! Did you ever dream there were so many applications of radioactivity? 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 Tuesday. Let’s finish the chapter tomorrow!

CHEMISTRY: So ordinarily it looks like just any old hunk of rock, but this is a picture of uranium ore under UV light. Pretty cool, huh?!? Here’s the lecture from Thursday on the properties of radioactive nuclides and the types of radioactive decay.
Hey, great job learning to write nuclear equations today! Don’t forget to memorize the nuclear symbols for alpha particles, beta particles (electrons), positrons, neutrons, and protons. I don’t think it will be nearly as bad as polyatomic ions! 🙂
Have any of you decided you want to get a head start on the half-life simulation lab? Don’t let it stress you out! It’s one of easiest labs you’ve done. But it does require that you READ the instructions on the syllabus and the website. If there is something you still don’t understand, make sure you ask me, I’ll be glad to help! And speaking of half-life, let’s calculate it tomorrow. Calculators ready!
CHEMISTRY: Happy new year and welcome to nuclear chemistry! We only barely got to begin today, but let’s finish talking about the properties of radioactive nuclides tomorrow. I think you’ll be surprised how much nuclear chemistry is already a part of your everyday life. And now you know where E=mc2 came from!!
Have you got a copy of the syllabus yet? It’s really important that you read it carefully – especially so you’ll know what to do about the half-life lab.
Here’s the brief intro lecture from Wednesday; we’ll finish the properties and begin talking about nuclear equations tomorrow. By the way, you need to read about the life of Marie Cure. Fascinating woman of science with an incredible story!
HON CHEMISTRY: Hmmmmm…..so what do you do when you forget to upload the day’s lesson to blip.tv? You post an old lecture from another year! This actually might turn out to be a good thing – the beginning of this old lecture has some half-life problems practice that might turn out to be useful for you. As for the rest – it doesn’t have everything, but it does have most of the applications that we talked about today in class.
So it turns out there are some pretty useful applications of radioactivity! Let’s finish talking about fission and fusion tomorrow, okay? Oh, and help session tomorrow morning, 7:15ish A.M.
HON CHEMISTRY: Welcome to nuclear chemistry! No, really, I think you’ll be surprised how much nuclear chemistry is already a part of your everyday life. And now you know where E=mc2 came from!! Here’s the lecture from Wednesday; we’ll finish the properties and begin talking about nuclear equations tomorrow. By the way, you need to read about the life of Marie Cure.
