In this lesson, students will plot and analyze the periodic properties (melting point, boiling point, density, electronegativity, and first ionization).

• Students will learn how certain properties of the elements tend toward a periodic similarity when the elements are arranged in order of increasing atomic number.
• Students will note the intervals between similarities and the relationship between similar elements.

• periodic table
• atomic number
• atomic mass
• ionization energy
• Periodic Law
• Z
• Z_eff

This lesson involves the periodic trends of certain properties of atoms.
As a result, students will:

• Graph pertinent data and observe the trends that occur.
• Answer questions to demonstrate their understanding of the periodic trends.
• Learn the Periodic Law.
