Particulate questions were used to investigate the strength of the metal association between the concept of compound and microscopic representations of molecules in students with different levels of chemistry preparation. Research subjects included undergraduate students enrolled in general chemistry, organic chemistry and physical chemistry courses at the Department of Chemistry of the University of Arizona as well as graduate students from different areas and stages in their degree program in the chemistry department. Focus was on the answers that students provided when asked to classify substances such as A2 and F4 as elements, compounds or mixtures. Overall, results show that a significant proportion of students in advanced chemistry courses misclassified molecular elements as chemical compounds.
