LAB 4B: Provided by Jim Moore, Tippecanoe High School Periodic Trends NAME: DATE: SCORE: PARTNER(S): PER: BACKGROUND: In 1870, Dmitri Mendeleev first proposed a new way of studying and organizing the then known 63 elements. The modern form of the table has been modified and improved many times since Mendeleev’s tables. Pioneers like Moseley (1913) and Seaborg (1941) have made the properties of the elements much simpler to study and understand. In this activity, you are going to discover some of the trends of the properties that exist on the modern periodic table. To do this, you are going to graph these properties. OBJECTIVES: The student will be able to… define some of the properties of the element graph the properties of the elements (use Z = 1 through Z = 36 only) determine the general trends found on the periodic table PROCEDURE: 1.On your calculator or in Excel , graph the trend of density . The graph should have the atomic number on the x-axis and density on the y-axis. Answer the questions about this graph and what conclusions you would draw. See the back of your textbook for density values. 2.On your calculator or in Excel , graph the trend of Melting Point and Boiling Point . The graph should have the atomic number on the x-axis and temperature (MP & BP) on the y-axis. Place both
