Materials:

  • Google Slides – students will learn how to find the number of energy levels (shells) for elements in periods 1 – 8 and the number of valence electrons in their outer shells using the periodic table. Updated (Public link)
  • Handout – updated Shells & Valence Electrons
    • Older version: How to determine the number of valence electrons and shells using the element’s group number and period – Notes (pdf) and Slides (ppt)
  • “Find that Element!” Worksheet (pdf)- Practice finding the period & group for each element

I updated the Google Slides and worksheet for my lesson on drawing Bohr Diagrams. This lesson will walk your students through the basics on how to draw a Bohr Diagram for the first 20 elements on the periodic table. I also created a simple worksheet for students to record their drawings and do independent practice.
