The modern periodic table is organized based on the periodic law, which states that the properties of elements are periodic functions of their atomic numbers. Each vertical column on the periodic table is called a group, and each horizontal row is called a period. The elements in a group have similar chemical properties due to their similar electron configurations. This is a characteristic of the modern periodic table. Choice A and B are incorrect because they incorrectly describe the definitions of groups and periods. Choices D and E are also incorrect because they incorrectly describe the location of the representative and transition elements on the periodic table, respectively.
