Element AI Authors Claudi Mans i Teixidó Abstract In this paper, a reflection is made about the different meanings of scientific terms, such as atom and element, and about the ambiguity of these meanings when used at different times in teaching chemistry. The discussion focuses on the fact that in many periodic tables, properties of the real element, as it is present in everyday life, are presented along with some properties of the element at an atomic level. Some recommendations are given in order to avoid the misconceptions that can be caused by these practices.
