A. Who developed the periodic table? How did Newlands organize the elements? By increasing atomic weight 2. What was his theory called? The Law of Octaves 3. Was it accepted? Why or why not? No, too many elements didn’t fit the pattern 4. What was his faulty assumption? He thought all elements had been discovered. 5. Who tried next? Mendeleev 6. How did he look for the pattern? By writing the information for each element on a card & laying them out in a pattern. 1. 11 3. 3 Periodic Table 9. 17. 00 1: 37 PM

7. How did he arrange the elements? By increasing weight and chemical properties 8. Horizontal rows were called what? Periods 9. What was true about columns? They were families with similar properties. 10. What did he assume the gaps to be? Undiscovered elements 11. What did he do regarding these gaps? Predicted the properties of missing elements 12. What change did Moseley make? He put the elements in order of atomic number instead of atomic weight. 12 3. 3 Periodic Table 9. 17. 00 1: 37 PM

Dmitri Mendeleev (1869) In 1869 Mendeleev and Lothar Meyer (Germany) published nearly identical classification schemes for elements known to date. The periodic table is based on the similarity of properties and reactivities exhibited by certain elements. Later, Henri Moseley ( England, 1887 -1915) established that each elements has a unique atomic number, which is how the current periodic table is organized. http: //www. chem. msu. su/eng/misc/mendeleev/welcome. html 13 3. 3 Periodic Table 9. 17. 00 1: 37 PM
