The term "periodic system" commonly refers to the Periodic Table of Elements, a tabular arrangement of the chemical elements organized by their atomic number, electron configuration, and recurring chemical properties. The term may also refer to various periodic systems in different fields, like economics or sociology, where regular intervals of observation or analysis are applied.
The frequency of use varies; "periodic system" is more prevalent in written contexts, particularly in scientific literature and textbooks.

The term "periodic" derives from the Latin word "periodicus," which means "recurring" and has origins in Greek "periodos" referring to "a going round" or "cycle." The word "system" comes from the Latin "systema," which means "a whole made up of parts." Thus, "periodic system" indicates a structured approach with recurring elements or components.
