HON CHEMISTRY: Can you guess what it is?/ It’s a picture of uranium ore under UV light. Cool, huh! Here’s the lecture from Thursday on the properties of radioactive nuclides and the types of radioactive decay. It also includes how to write nuclear equations. Don’t forget to memorize the nuclear symbols for alpha particles, beta particles (electrons), positrons, neutrons, and protons. Not nearly as bad as polyatomic ions, huh?!? 🙂
I thought you might want to get a head start on the half-life simulation lab, so I posted about that earlier. I’m including a copy of the Half-Life Simulation Lab here, but make sure you go back and read that post for detail that you will need. And speaking of half-life, let’s calculate it tomorrow. Calculators ready!
In our book, it says a particle accelerator in Illinois is 4 miles long in circumference. Why is it so big?
Is there some sort of decay in which you add/subtract neutrons because it was in one of our homework problems?
In electron capture, how does the atomic number of the atom decrease yet not lose any protons?
Hey Ms. Skinner, when an element decays, can it decay into other elements and return to its original element after going along the series of decay?
Hey Mrs. Skinner, i don’t understand the half life’s of the radioactive elements we talked about in class. Like how do you know the exact time length it takes for it to decay to it’s half life?
Will we have a help session before the test?
Ms. Skinner, do you want our procedure to be in paragraph form or in step form (1,2,3)?
Adam – Yes, the procedure is always in paragraph form, like a journal. The observations are what might be in different formats depending on the type of lab.
