Hon Chemistry 1-18-19 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!

And 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”! Let me know if you figure out the riddle!!

Chemistry 1-18-19 Half Life Problems

CHEMISTRY: These banana’s been through too many half lives for you?? Great job thinking through the half-life problems! Be sure and practice, practice, practice! They aren’t super difficult, but if you don’t practice, you’ll be as lost as a ball in high weeds!!

What about the Half Life thLab? Now may be the time to get started since next week will be a busy week! Be sure and read the lab ahead of time so you’ll be prepared with the materials you need. I’ll post where you’ll put your results next week.
