This article is a review articles on three levels of chemical representation until 2020. The method used in this research is document analysis. We obtained 72 articles published within 11 years (therefore, 2009-2020) that discussed the level of chemical representation. The results obtained were 50.67% of researchers using the term macroscopic, submicroscopic, and symbolic levels which were different from the original ideas of Johnstone. In addition, we found 15 new terms for 3 levels of chemical representation. Furthermore, the scope of macroscopic, submicroscopic, and symbolic levels becomes richer and broader.
