Experiment: Periodic Table Trends Investigation

In this experiment, we will investigate periodic trends of chemical elements using the Periodic Table. We will focus on atomic radius, electronegativity, and ionization energy to understand the arrangement and properties of elements.

Materials:
  • Periodic table
  • Reliable source of element data (chemistry textbook, reputable online database)
  • Graphing software or graph paper
  • Calculator (optional, for data manipulation)
Procedure:
  1. Select ten consecutive elements from the periodic table. These can be from the same period or group.
  2. Record the atomic number for each selected element.
  3. Find the atomic radius, electronegativity, and ionization energy for each element using your chosen data source. Note the units for each property.
  4. Create three graphs:
    • Graph 1: Atomic number (x-axis) vs. Atomic radius (y-axis)
    • Graph 2: Atomic number (x-axis) vs. Electronegativity (y-axis)
    • Graph 3: Atomic number (x-axis) vs. Ionization energy (y-axis)
  5. Analyze the graphs to identify trends in atomic radius, electronegativity, and ionization energy across the selected elements.
  6. (Optional) Compare your findings to established periodic trends discussed in your textbook or other reliable sources.
Step-by-Step Details:
  1. Choose ten consecutive elements. Clearly state which elements you have selected and whether they are from the same period or group.
  2. Carefully record the atomic number and the three properties (atomic radius, electronegativity, and ionization energy) for each element, citing your data source.
  3. Construct accurate graphs. Label axes clearly (including units), provide a title for each graph, and use appropriate scales.
  4. Analyze the trends observed in each graph. Describe the observed patterns in terms of increases or decreases in the properties as atomic number increases. Consider whether the trends align with expected periodic trends.
Significance of the Experiment:

This experiment provides a visual and quantitative understanding of periodic trends. Analyzing these trends helps predict the chemical behavior and reactivity of elements. It demonstrates the relationship between an element's position on the periodic table and its fundamental properties, reinforcing key concepts in chemical bonding and reactivity.

Further Considerations: This experiment can be extended by investigating trends across different periods or groups, or by comparing the trends for different sets of consecutive elements. The selection of elements significantly influences the observed trends. Discussing potential sources of error and limitations of the data used is also important.
