South Pasadena Chemistry Name _______________________________ Period ___ Date ___/___/___ The Periodic Table -- A Simulation INTRODUCTION Dmitri Ivanovich Mendeleev, A Russian scientist, was able to organize the elements into a system based upon first grouping the known elements by similar properties and then ranking by increasing atomic weights. The first part of this activity illustrates the ideas of grouping versus ranking by using playing cards. For the second part of this activity, you will become a scientist in the year 1869. The known elements are written out on cards with properties of each element. The goal is to group the cards by oxygen combination properties and then rank the cards by increasing atomic weight. The final steps will be to expand the table into the periodic table. Mendeleev was very bold for his time. His periodic table was such that he could predict elements not yet discovered and give properties of those elements based on the position of the missing element in the periodic table. Task 1: Ranking and Grouping
