Abstract: From the discovery of chlorine gas in 1774 to its recognition as a new element in 1810, chemists were influenced by the prevailing chemical theories of the time, which led to varying interpretations of chlorine. By reviewing relevant literature, this paper traces the early history, from the discovery of chlorine to the formulation of the concept of the chlorine element, and explores the impact of contemporary chemical theories on the development of the chlorine element concept across different historical periods.

Key words: Chlorine, Chemical history, Chemical theory, Paradigm
