The periodic table is arranged by a specific concept: “The properties of elements are repeating functions of their atomic number.” This is known as the periodic law. This creates a set of patterns on the periodic table called trends. These trends include electron configuration, electronegativity, ionization energy, and atomic radius. This activity is designed to teach students about the atomic radius via the inquiry method.
Rather than just lecturing about the periodic trends, or having the students do boring worksheets, they get to explore it on their own. Students will love discovering the facts that make the periodic table such a powerful tool.
