SUMMARY:

Historically, the concepts of atom and chemical element were related by the theories of primordial elements/principles and the atomistic theory. Even though we knew that "element" had a different meaning than what we understand today, these discussions helped to understand aspects of the matter. It was not until the eighteenth century that Lavoisier made a distinction between this concept and that of simple substance, a confusion that recurs even today. Thus, the work aims to: Analyze processes of conceptualization for chemical element, from the relationship between the different ways of thinking and ways of speaking the concept of atom, experienced by undergraduate students in chemistry engaged in a sequence of teaching and learning. This main objective unfolds in other research intentions, such as: To identify meanings and senses attributed to the concept of chemical element and zones of the conceptual profile of atom by students of the discipline of history of chemistry; To analyze processes of conceptualization for atom and chemical element experienced by undergraduate students in chemistry in the process of a sequence of teaching and learning; To organize relations between commitments implied in the ways of thinking about the chemical element with the zones of the conceptual profile of the atom that may be of an epistemological, ontological and/or axiological nature. For this, assumptions of the Theory of Conceptual Profiles and relations between senses and meanings established in discursive interactions in the classroom will be considered as constitutive components of the conceptualization process. A qualitative methodology will be adopted for data recording and analysis, based on a sequence of teaching and learning. Applied with students of the discipline of history of chemistry, of the degree in chemistry of the Federal Rural University of Pernambuco (UFRPE). The audio recordings were transcribed for analysis and, in addition, questionnaires and dialogues based on a case study provided the database. In order to analyze the convergences and dissonances of the different ways of thinking about chemical element and atom, as well as the importance for the conceptualization process of students from the analytical tool developed by Scott and Mortimer. The results demonstrate a relationship between the concepts of atom and chemical element through the compromises identified in the students' responses to the research instruments, as well as the interaction in the sequence of teaching and learning demonstrates the conceptualization of these concepts.
