CHEMISTRY: Hey guys, you’re really doing a great job connecting the dots with Lewis structures! Here’s the lecture on polyatomic ions. Don’t forget to count the electrons! And then double check the number of electrons. And when you think it’s right, count the electrons!! 🙂
HELP SESSION tomorrow morning (Thursday) at 7:15. Come if you’d like some extra practice or some help!
HON CHEMISTRY: Hey guys, great job with Lewis structures, multiple bonds, resonance, and polyatomic ions today. Wow, that was a lot! Here’s some good advice – don’t take shortcuts. Learn the proper steps on the easier molecules, and you’ll be able to do the hard ones. And if it’s still all Greek to you, don’t worry! Keep practicing and you’ll get it, I promise!! Don’t forget to count electrons and don’t forget CONS!
CHEMISTRY: Great job today! Do you understand better now? Remember – baby steps, first binary ionic compounds, and now, formulas with polyatomic ions. Begin learning them now! And practice, practice, practice!!
HON CHEMISTRY: Are you starting to see numbers in your sleep? Here’s the lecture from Monday on writing chemical formulas with polyatomic ions, and also an intro to binary molecular formulas. The same, but different……huh? Tons of memorization for this chapter – monatomic ions, polyatomic ions, prefixes, and this is just the beginning. Good luck, and keep practicing!!!
