This worksheet is the BEST!!! It shows students a few different things:
1: Electrons always fill the inner-most shell first, then work their way out.
2: 2, 8, 8 electron shell pattern
3: Basic structure of the PTofE
4: Patterns of valence electrons in the PTofE
Don't lecture students on all of these facts; first have them complete this worksheet, then hold a group discussion on the patterns they found. The worksheet takes approximately 1 class period to complete.
Discussion can occur same day or the next day depending on whether they use a pencil or a thick marker (recommended... see below), and how long it takes them in general.
I have included a page with the directions, which I typically put in the blank space on the second page. In the first box, I left a blank page number in case you have a section in your textbook that you would like your students to read before completing the worksheet. If you don't have a section of a book you want them to read, then use the second set of directions. Or you can write you own!
Recommendation: Have students color in (well, just tap) the dots using a thick marker- takes less time and there is significantly less hand hurting by the end of the task (even though hearing the complaints from the students can be entertaining...) ; )
I originally was selling this item, but I really don't like how little us teachers make on our products versus how much goes to the website and paypal : ( So now it is available to you for free! If we all paid $1.00 for every worksheet or lesson we presented to our students.... well we would be out a lot of dollars. So here you go. I hope you enjoy the worksheet as much as I did (I now teach a different subject).
