Chemistry Unit – Periodic Table, Valence Electrons, Periods, Groups, Lewis Diagrams and More!
150+ Page Chemistry Packet!
I am excited to share our new chemistry unit with you! (It has been recently updated and now is around 150 pages!!) As you know, we love hands-on activities and I want to show you some of the fun ways we explored the periodic table and touched on topics like valence electrons, Bohr Diagrams, Lewis Diagrams (electron dot diagrams), ions, isotopes, and more!
Some of the topics we explored included:
- Building the Periodic Table
- Bohr Diagrams & Understanding Valence Electrons
- Periods, Groups & Families
- hydrogen & the alkali metals, alkaline Earth metals, halogens, noble gases
- Atomic Number, Atomic Mass & Chemical Symbols
- Lewis Diagrams
- Metals, Metalloids and Nonmetals
- Unusual Element Symbols
- Trends of the Periodic Table
- Electron Configuration

Note: Chemistry for Elementary — My youngest enjoyed the unit, but some of the topics we touched on as the unit went on were a bit above her head. (She still wanted to participate but acknowledged it was challenging for her!) Be sure to this post Fun, Simple Science Experiments for Younger Kids! (Introducing Kids to Chemistry) if you have younger kids (It has a free Chemistry Experiment Packet for young learners.)
The First 20 Elements and Elements with Unusual Symbols:
Update: There are two new chemistry booklets on the first 20 elements and on elements with unusual symbols in this packet. My youngest was in 5th grade she worked on these pages. 🙂
She used a beautiful book about the elements by Theodore Gray Elements: A Visual Exploration of Every Known Atom in the Universe (affiliate link) as a reference. It has huge pictures of the elements as well as pictures of items that use this element.
This booklet had her find out: the atomic number, atomic weight, period and group numbers. Plus, there was some space for her to write some basic facts about each element.
My 5th grader also spent some time building molecules.
- We have the Molecular Model Kit (affiliate link) for building molecules.
Period Table Hands-On Activities
This was the first activity we did as we started looking closely at the Periodic Table:

Note: There are cards for the elements 1 (hydrogen) through 36 (krypton) included in the Chemistry Packet.


- each row/period added on “shell” (or ring) around the nucleus
- each column/group had the same number of electrons in the outer ring (except for helium)
Note: There are Bohr Diagram cards for elements 1 (hydrogen) through 20 (calcium) included in the Chemistry Packet.

They also did the worksheet I made for them which has them look at the number of shells and number of valence electrons various elements have.


We went on to talk about Lewis Diagrams. These are similar to Bohr Diagrams, but only provide information about the valence electrons (the outer electrons of an element). By this time, the kids were able to whip through this worksheet (using the Bohr Diagram cut-and-paste activity above):

Our next topic was about metals, nonmetals and metalloids and how this information can help us understand different types of bonds that are formed. We talked (briefly) about covalent and ionic bonds. We talked about that in covalent bonds electrons are shared, which in ionic bonds atoms give their atoms away. It was beyond the scope of this unit to go into much more detail than this, though I did touch on electronegativity charts. We looked at the Pauling Table and talked briefly about how that chart can help scientists determine/understand the types of bonds that are formed. (There is a page about that in the chemistry packet.)


One afternoon, I brought out some ping-pong balls and cups. The kids thought that was funny and enjoyed trying to bounce the ball into the correct cup! 🙂 Below you can also see some of the chemistry review cards I made for the kids (with many of the terms they learned during this unit… from proton and neutron to halogen, covalent bond, and anion and atomic number.
You might end your chemistry unit there or you can go on to talk about electron configuration.
With my older two (and now with my youngest, age 13), we talked about electron configuration & electron notation. (For example, oxygen is 1s2, 2s2, 2p4 — does that ring a bell from you high school chemistry days?!)
My kids thought it was tricky at first, but then quickly got the hang of it.
I have just updated this section to add in a number of colorful sheets (that go along with the s-block, p-block, d-block and f-block colors on the reference pages):

Here are a few close-ups of this material:

Do I need any specific books with this unit?
No, our notebook pages and worksheets include answer pages and teacher notes. There are several chemistry resources I’m glad I had on hand, though. These are affiliate links:

Chemistry Homework Helpers by Greg Curran – This is fairly advanced (and I didn’t use it with the kids), but was really useful for me as the instructor.
Glencoe Chemistry Matter and Change – I purchased quite a number of used high school chemistry textbooks (8!! Crazy right?!!) and after going through these, the one textbook we wound up using a lot (for my high schoolers) was this textbook. It has all the answers to the practice problems in the back (not just the odd answers!). We used this A LOT when my kids covered high school chemistry, but I was glad I purchased it when my kids were in middle school so I could use it as a reference.
One Mom asked if this packet is suitable for someone with little to no chemistry knowledge.
Here was my answer! Yes! I provided all of the answers and actually added in quite a number of teaching hints along the way. I designed the activities so that the kids discover some of the patterns of the Periodic Table themselves. (That’s why Bohr Diagrams are really useful, if a little outdated in our knowledge of atoms!)
In this packet, I have a general guide at the beginning of the packet of what we did on day 1, day 2, etc. b/c I thought some parents might want a bit more guidance. I tried to make it pretty straight-forward (so even wrote out instructions for what I said to the kids on certain days and what hints I gave to help them discover the answers/patterns for themselves.
