Chemistry 5-9-23 Noble Gas Notation

CHEMISTRY – Great job with noble gas notation today!! Watch this vodcast again and it will make even more sense the second time! It would also be great review for the test! Speaking of which – have you checked out the stuff to know sheet for the test??? Super important!!!

Need extra practice or help? Wave problems? Electron configuration?? Help session this Thursday, 7:30ish A.M.

Hon Chemistry 5-9-23 Intermolecular Forces, Pt 2 & Ionic Bonding & Help Session

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!

Under today’s vodcast – the help session from this afternoon and our practice with Lewis structures.
