  1. You're welcome! He would definitely appreciate the second link, then. πŸ™‚ I hope he (and you) enjoy them!
  2. If he's working at that level, then this might be a better playlist of videos for him to watch: https://www.screencast.com/t/1qCmZkCM Those are the ones on electron configuration from my Honors Chem course (the other playlist was from my reg Chemistry course). πŸ™‚
  3. These are some videos on the topic of electron configuration: Your second question is definitely a big one and it's very dependent on your student and on the specific course. I could take your list of topics and create sublists giving all the major stumbling blocks that I've seen students have... but that would end up being a small book. πŸ˜‰ The above video playlist is from one of my online courses - teaching chemistry to homeschooled students is what I do for a living. πŸ™‚ In general, though, I'd say to remember that chemistry builds - early topics like mole calculations,
  4. Yes. πŸ™‚ That string of numbers and letters is called the electron configuration. It tells us where all the electrons are located in an atom. (Well... sort of. It's actually way more complicated and weirder than that because now we're getting into quantum mechanics. But for our purposes, we'll just say it gives the locations of the electrons. :)) The first number is called the principal quantum number. It's the number of the energy level that the electrons are located in. Energy levels are actually further divided into what are called subshells (this isn't mentioned in many intro che
  5. I'll answer your questions in order. πŸ™‚ 1. (a) No. πŸ™‚ If water is reacting with an alkali metal (first column on the periodic table minus H) then the products will be a hydroxide and H2(g). Water can also react with lots of other things to produce other products, though. 1. (b) No. πŸ™‚ Most of the reactions of water that you'd be looking at in basic introductory chemistry would be reactions of water with metals (or metal oxides) and reactions of water with nonmetals (or nonmetal oxides). In the second case, though, some of the nonmetals (or nonmetal oxides) could be gases, not solids
  6. I keep meaning to put aside some time to fix up/update these threads and I never seem to get to it! So sorry about that! I'll take out the LabPaq references right away. Edit: Just realized the LabPaq reference isn't in a post of mine. If you tag the author, MamaSprout, you could probably get them to remove the reference.
  7. Hi all! πŸ™‚ I know - I disappeared. Things have been crazy. Books have been read (but I haven't kept track and so don't have an updated list - will try to do that soon). House/farm were cared for. Gardens were planted, harvested, and now need to be cleaned out since we had our first hard frost last night. Child was home from university for almost 6 months but went back on Monday. She's 5 hours away. In a city where COVID cases are climbing. I can do this. Breathe. I just wanted to say that the fact that this thread was here each week and I could pop in and read a bit whenever
  8. @AsgardCA - what province are you in? You're welcome to PM me if you don't feel comfortable stating that on the public forum. πŸ™‚ I graduated my daughter from our homeschool in Ontario in 2018 and she did not go the GED route. Because I knew she was headed for university and then post-graduate studies, a GED would have been seen as odd. She did, however, take the SAT and had 6 AP exams scores on her transcript as well as scores from the Royal Conservatory of Music (she's a piano performance major). Universities in Ontario don't require the student to have any kind of "official" high school
  9. My degree is in organic chemistry. πŸ™‚ It's... uniquely challenging. Students who are strong mathematically run into a wall because it isn't an intuitive type of course and students who are strong in the biological science run into a wall because (probably) they've been led to believe that OChem is mostly memorization (which they're probably good at) - but it isn't. It's that bizarre combination of being detailed oriented (similar to biological sciences) with also leaning heavily on logical and deductive/inductive types of thinking (similar to physical sciences). OChem I and II are usual
  10. The transcript thing is probably dependent on what his high school is willing to do and what he needs for applying to the colleges he's interested in. @Lori D. or @Farrar might have a better idea on how to handle that.
  11. The Organic Chem/Biochem course is $650 for a 36 week course. And AEC gave a great description of grading and parent involvement. πŸ™‚ @AEC - let your DD know that Mrs. S and Chemistry Mole say hi and that we're so excited that she's doing AP Chem! If she wants to ask any chem questions of me during the year, she knows my email address! πŸ™‚
  12. Someone else recommended my Organic Chem class - thank you to the recommender! πŸ™‚ I originally created the course for my daughter when we were homeschooling because she wanted to eventually apply to med school. She's now a rising junior at university (and will be writing the MCAT for the first time in January) and she told me that taking some organic chem and biochem in high school with me really helped her when she took those classes at university. πŸ™‚ If the OP would like to pass this link on to her nephew, he can see what he thinks. https://clovervalleychemistry.com/introdu
  13. The Brown/LeMay text is a good AP Chem text. πŸ™‚ I tend to prefer Chang but that's just personal preference, not because it's better. The Zumdahl AP Chemistry textbook is also good: https://ngl.cengage.com/search/productOverview.do?N=201+4294918395&Ntk=NGL|P_EPI&Ntt=9781305957732|10860011361047768559138144486101779192&Ntx If you do decide to go with Chang, make sure to get his AP textbook and not his gen chem book. The AP text is this one: https://www.mheducation.com/prek-12/product/chang-chemistry-ap-edition-raymond-chang/9780076619986.html There are a number
  14. I have worksheets I can send to you, if you wish. πŸ™‚ There's also this website which lets students practice naming, writing formulae, and even calculating molar mass: https://www.kentschools.net/ccarman/cp-chemistry/practice-quizzes/compound-naming/ For naming, you can choose how many practice questions you'd like and whether you'd like to name molecular compounds, ionic compounds, or acids (or any combination of those). Have fun naming! πŸ™‚
  15. That's a big Akbash! My two are Pyr/Akbash crosses and my male is close to 150 lbs. He looks much more like a Pyr, though. My female definitely looks more like an Akbash and she's somewhere around 90-ish lbs. WORD. Show me a trainer getting a consistent recall on a Pyr who has spotted something way out in the pasture and THAT will impress me. πŸ˜‰ πŸ˜„
