CHEMISTRY: Wow – super short class! 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.
