Name:
Mendeleev’s Table
Introduction:
In 1869, aware of the need to organize elements in a meaningful way, Dmitri Mendeleev
developed a classification scheme based upon increasing atomic mass. Elements that
demonstrated similar patterns of chemical behavior were placed into eight groups. Members of
these groups were displayed in vertical columns of his periodic table. Even though his chart was
incomplete, Mendeleev was able to predict the properties of elements yet to be discovered. Over
the next two years, Mendeleev published modified versions of his original periodic table.
Today’s periodic table accommodates at least 50 additional elements. Although the scheme is
based upon increasing atomic number, the arrangement of elements within the chart is similar in
organization to the table published by Mendeleev in 1871. Your knowledge of the modern
periodic table and facts about the elements will allow you to construct the periodic table
published by Mendeleev in 1871.
Procedure
The positions of the elements found on Mendeleev’s 1871 version of the periodic table
are coded for the chart shown on the next page of this lab. The following clues will help you to
identify the elements. Identify each element and write the name and symbol for it on the lines
next to each clue. Then record the symbol in the copy of Mendeleev’s periodic table provided.
Your textbook has some Latin names on page 52, and a Periodic Table on page 162. Also,
Appendix A might be very useful, along with the data given in the Reference Tables.
