The present work presents a research on the learning and teaching of atomic models and aims to elaborate and evaluate a module of study of historical and epistemological aspects about atomic models in the formation of chemistry teachers. Initially, it describes and discusses the results of a survey of alternative conceptions of university students of chemistry on the subject and, based on this analysis, presents a didactic text on historical and epistemological aspects of the atomic models, as a way of minimizing the learning problems detected in the sample Investigated and literature on the subject. The results of the survey showed that subjects, like other similar studies, do not adequately understand the nature, history and context of application of the different atomic models. In the case of the sample investigated, as it is about future chemistry teachers, this is a very worrying fact. On the other hand, the results of a small sample of university students, who willingly read the text and answered questionnaires, indicate that the reading of historical and epistemological information presented in the text did not help to found in the conceptions of these future professors of chemistry.
