Mendeleev Activity

Mendeleev Activity
Periodic Table Unit


Students will be able to…
• Construct a portion of the Periodic Table (Elements #1-20, 31-36) using the trends given on “Element Cards.” Note: Students should not use a Periodic Table for this activity!
• Construct a portion of the Periodic Table (Elements #1-20, 31-36) but leave blanks in the Periodic Table representing two unknown/missing elements. Students will then predict the properties of the missing elements.
• Describe Periodic Law, how Mendeleev ordered the Periodic Table, and how Mendeleev predicted properties of undiscovered elements.
• Investigate Periodic Table trends: atomic number, atomic mass, boiling point, melting point, state of matter, metal/nonmetal/metalloid, density, color, ionization energy, electron affinity, electronegativity, reactivity, Noble Gas Configuration, valence electrons, Lewis symbol, Bohr diagrams, ion charge, atomic radius

Additional Required Materials
(These items are not included in the purchase.)
• Cardstock – for printing “Element Cards” and “Periodic Table Labels”
• Lamination (optional)
• Baggies / Activity Storage container


Teacher Preparation:

(1) Pick a Version of the Activity
• This activity is easily customizable. Start preparing by determining what information you have covered as well as what information you wish for students to learn from this assignment.
• Pick out a version of the “Mendeleev Activity WS” for students to complete. The assignment can also be shortened by only assigning the first three pages (Part I of the WS).
• Pick which set of “Element Cards” to use – regular or challenge cards. Pick which “Periodic Table Labels” to use.

(2) Print on cardstock all “Element Cards” and “Periodic Table Labels” and laminate (optional). Also print a “Mendeleev Activity WS”.

(3) Put Together the Mendeleev Activity in Baggies (or another storage container).
• Recommend making 15 Mendeleev Activity Kits so students can complete in pairs.
• In each kit, place 24 element cards. There are 26 total element cards (elements #1-20, 31-36). You pick two element cards to leave out of each kit. These will represent the missing elements. Each kit can have the same two missing elements OR each kit can have different missing elements. Make sure the two elements come from different groups! Preferably, one missing element on the right side and one missing element on the left side of the Periodic Table.
• In each kit, place the “Periodic Table Labels”. If there is a trend/topic that has not yet been covered in your classroom…then do NOT include those labels in the kit.
• On each baggie/kit container, write the number of “Element Cards” and “Periodic Table Labels”. At the end of the activity, students can then be responsible for counting to make sure they have the correct number of cards placed back in the kit.

***Students may NOT use a Periodic Table at any point during this Activity!!!***
