Chemistry 4-2-12 Ionic Bonding

CHEMISTRY: Hey guys, here’s the lecture on ionic bonding – well, the first part anyway. Remember, when you write ionic bonding, you’re not trying to arrange a single structure like you do with Lewis structures. Instead, you’re writing an equation that shows electrons being lost by one atom and gained by another atom. Make sure you put the dots in the right order. We’ll finish metallic bonds tomorrow.

UPDATE: Here’s an updated vodcast on ionic bonds – hopefully the sound will work on this one.

Chemistry 3-22-12 Intro to Chemical Bonds

CHEMISTRY: Welcome back to chemistry! Ready to begin another chapter? Here’s the first lesson from chapter 6, the introduction to chemical bonds. Patience! We’ll get to the good application stuff in just a bit!

BTW – Homework goes with what we did today: Pg. 209 – 213: 1 โ€“ 8, 10 – 15. And don’t forget the Science In the News for tomorrow!

Hon Chemistry 2-28-12 Ionic Bonding

HON CHEMISTRY: Hey guys, here’s the lecture from Tuesday on ionic bonding. Wow, we missed a whole bunch of you. Hope you get well soon, I don’t like having class without you!

Back to ionic bonds – keep in mind that when you write ionic bonding, you’re not trying to arrange a single structure like you do with Lewis structures. Instead, you’re writing an equation that shows electrons being lost by one atom and gained by another atom. And make sure you put the dots in the right order!

Also important, pay close attention to the comparisons of ionic and covalent bonds – and WHY! And whatever you do, stay away from bubble baths if you have mortal enemies!

Hon Chemistry 2-16-12 Intro to Chemical Bonds & Covalent Bonding

HON CHEMISTRY: Hey guys, here is the lecture on the intro to chemical bonds, electron dot notation, and covalent bonding. Make sure you add the diatomic molecules to your “things I have to memorize for the test” list. We’ll tackle Lewis structures tomorrow! ๐Ÿ™‚
