Periodic Table Affinity Mapping

Teacher instructions

  1. Students will work silently and independently to answer questions about valence electrons and atomic orbitals
  2. Students will each pick 5 cards from the center of the table and silently work to organize their cards into piles with group members
  3. Students will then talk with their group and work to create a system for organizing the cards
  4. Students will use the remaining cards to complete their arrangement.
  5. Students will write an explanation of how their group developed their system
  6. Students will compare their arrangement of the elements to the actual periodic table write a comparison of the two arrangements.

Student Instructions

  1. Complete the following questions on your own paper.
  1. What is a valence electron?
  2. What is an electron orbital or shell?
  3. Copy the diagram below and label the: protons, neutrons, electrons, electron orbitals, valence electrons.

 

  1. Select 5 cards from the center of your table (there will be cards left)
  2. Silently working with your team members, arrange all the cards that were picked up into groups.
  3. Talk with your team and discuss why you grouped your elements in the way you did.
  4. Work together to create an arrangement that will organize all of the cards that group members selected into a system. If you think that there is a hole in the system leave a blank space.
  5. Use the remaining cards on the table and try to fit them into your arrangement based on the system your team designed.
  6. Answer the following questions on your own paper.
  1. How did your group arrange the elements?
  2. Why did you arrange them in this way?
  3. Compare your arrangement with the actual periodic table found on page 874 in your textbook. How does your arrangement compare to that of the periodic table? Why do you think that is?
