Periodic Table

Periodic Table. It is a systematic catalog of the elements. Elements are arranged in order of atomic number. Periodicity. When one looks at the chemical properties of elements, one notices a repeating pattern of reactivities. Periodic Table. The rows on the periodic chart are periods.
