Hon Chemistry 4-20-26 Intermolecular Forces, Pt 2 & Ionic Bonding

HON CHEMISTRY: So how ’bout Johannes van der Waals and those intermolecular forces? Tons of application, from bugs walking on water to little fishes breathing dissolved oxygen. And what about the condensation that forms on the outside of an iced tea glass? Hmmm….

And then on to a different way that atoms come together – ionic bonding. 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!
