Periodic Table Review Return to Table of Contents Slide 5 / 130 Periodic Table - Review The periodic table is "periodic" because of certain trends that are seen in the elements. Some of these trends can be seen in the properties of atoms we covered in the last unit: atomic size, ionization energy, electronegativity and metallic character.

E. Modern Periodic Table 1. Modern Periodic Law: similar properties of the elements occur periodically when arranged by their atomic numbers (not masses) 2. The arrangement of the periodic table is now based on how electrons fill various energy levels 3. Organization: a. Period: horizontal row of elements by increasing atomic number;

Objective: To understand trends of the periodic table and practice methods of graphing. Background The Periodic Table is arranged according to the Periodic Law. The Periodic Law states that when elements are arranged in order of increasing atomic number, their physical and chem
