Chemistry 1-18-17 Radioactive Decay

CHEMISTRY: Today has been all about arrows for some reason! So how are you doing with the nuclear equations? Feeling better about them now that you know what side of the arrow to put the particle on? Also, make sure you memorize the nuclear symbols for alpha particles, beta particles (electrons), positrons, neutrons, and protons – those are just as important as the arrow! Need extra help? Help session Friday morning, 7:20ish A.M.

Be sure and bring a calculator tomorrow – we’ll tackle half life problems! 🙂

Hon Chemistry 1-18-17 Orbital Notation & Electron Configuration Notation

HON 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”!!!
