Abstract
This paper analyzes the learning difficulties of students in secondary education about the subject of the Periodic Table of elements. We present the opinions of a sample of teachers in Chemistry and Science Education obtained from written questionnaires and semi-structured interviews. The information has been analyzed from a set of eight dimensions that allow us to systematize several sources of difficulty and different reasons that may hinder student learning in this subject. Specifically, we propose these dimensions: 1) attitudinal aspects, 2) memorizing 3) deficiencies about preconceptions in the lesson 4) misunderstanding of the properties used as criteria classification; 5) the notion of periodicity and the perception of its usefulness 6) ambivalence of meanings of notions related with the Periodic Table; 7) the abstract nature of the concepts involved and the reasoning required; and 8) deficiencies in the teaching process.
