maize Posted February 9, 2020 Share Posted February 9, 2020 Dd16 is struggling to understand electron shells, subshells, orbitals, valence electrons, and how these all relate to the periodic table. I tried to help her sort it all out yesterday but she is still confused. Does anyone have a super clear way of explaining all this, or maybe a link to a good explanation?

Dicentra Posted February 9, 2020 Share Posted February 9, 2020 https://www.screencast.com/t/LOIDSuVf These are my reg Chem videos on that topic. 🙂 She is welcome to start with the first video but it's just on the different types of electromagnetic radiation. The second video (Section 5.3) is where I begin explaining shells/subshells/orbitals, etc. I use my "patented" 🙂 bus analogy. It seems to work fairly well and gives kids a concrete visual to hang all of those abstract concepts on. 6 1 Quote Link to comment Share on other sites More sharing options...
ElizabethB Posted February 9, 2020 Share Posted February 9, 2020 I would buy a used copy of RS4K Chemistry Level II, Junior High level. The explanations are very clear, with pictures for most big picture things. When I did High School Chemistry with my daughter, I was doing this level of Chemistry with my son, anything my daughter didn't understand, we went to her brother's book to explain. You can get a used copy cheaply. https://www.amazon.com/gp/product/097650975X/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 3 Quote Link to comment Share on other sites More sharing options...

klmama Posted February 10, 2020 Share Posted February 10, 2020 Here is a YouTube channel that we've found helpful for chemistry: The Organic Chemistry Tutor. 2 Quote Link to comment Share on other sites More sharing options...
cintinative Posted February 10, 2020 Share Posted February 10, 2020 (edited) I felt like the discussion of this in Middle School Chemistry by ACS was easy to grasp. There are some brief videos/models here. Since it is written for a younger age, maybe this will help it click better? https://www.middleschoolchemistry.com/lessonplans/chapter4 Here is one example of how they show valence electrons from "The Periodic Table and Electron Filling" from this link. I would give her that (it's a pdf) and see if it helps. Edited February 10, 2020 by cintinative 3 Quote Link to comment Share on other sites More sharing options...
SanDiegoMom Posted February 10, 2020 Share Posted February 10, 2020 Seconding Dicentra's videos -- my son learns best by teaching me, so he taught me according to her explanations. And I understood it. And I slept through high school chemistry and was an English major. 🙂 3 Quote Link to comment Share on other sites More sharing options...
Arcadia Posted February 11, 2020 Share Posted February 11, 2020 If she absorb better with some hands on fun, the Nova Elements iPad app was fun.

Dd watched your video this week, she said it was much easier to understand than the other explanations she had found. Thank you again! 2 Quote Link to comment Share on other sites More sharing options...
