Chemistry: understanding electron shells and valence electrons

Recommended Posts

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?

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.

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.

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?

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.

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.  🙂

Dd watched your video this week, she said it was much easier to understand than the other explanations she had found.

Thank you again!
