Hon Chemistry 1-6-15 The Electromagnetic Spectrum & Wave Properties of Light

Posted on by

HON CHEMISTRY: Isn’t this a super cool picture of light? So tell me again, if we’re supposed to be figuring out electrons, why are we studying waves?

I’m thinking you’ve probably memorized the electromagnetic spectrum after that inspirational song; however, also sure you also know the uses of the different types (all except for long waves). Just in case you’d like to hear it again: Electromagnetic Spectrum Song

This other video clip on The Electromagnetic Spectrum also gives you a really unique look at the electromagnetic spectrum and begins to connect the Spectroscopy lab from last semester to what we are going to learning about in this chapter.

How’d you like the light problems so far? We’ll explore waves further tomorrow – make sure you bring a calculator to class!

Chemistry 1-6-15 Radioactive Decay

Posted on by

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 on the properties of radioactive nuclides and our beginning discussion on the types of radioactive decay.

Don’t forget to memorize the nuclear symbols for alpha particles, beta particles (electrons), positrons, neutrons, and protons – you will need them to write nuclear equations. 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 (The post on the website will be up soon, be sure and look for it.). 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 do some calculating tomorrow. Calculators ready!
