Hon Chemistry 5-4-21 Electron Affinity, Ionic Radii & Electronegativity

HON CHEMISTRY: So you’re saying, not only are there atoms that want to get rid of electrons, there are atoms that want to take them? Here’s a picture of chlorine taking an electron from sodium – or sodium giving an electron to chlorine. I’ll let you decide!

Hon Chemistry 5-4-21 Periodic Trends, Pt. 2 & Chemical Bonds

HON CHEMISTRY: Here’s the last of the trends – not car trends, periodic trends! 2nd ionization energy, electron affinity, ionic radii, and electronegativity. Whew!

Now on to the next chapter and welcome to chemical bonds! How did you do on using electronegativity to determine bond type? Make sure you add the scale to your “things I have to memorize and know how to use for the test” list.

Physics – Your LAST Web Post Comment!!

PHYSICS: Can you believe it?!? This is your LAST web post comment!! This is where you put it and here are the three things I want you to talk about:

1) How did physics grow you? What did you learn about yourself?
2) What advice do you have for future physics students?
3) What could we have done different this year that would have helped you learn physics better?

Can’t wait to hear from you!! 🙂
