A simple laboratory experiment illustrating the relative nature of atomic weights Huff, Randolph B.; Evans, David W.
The concept of atomic weight scale remains a source of confusion for beginning chemistry students. This paper proposes a simple lab experience that could help students better understand this idea.

Is an atom of copper malleable? Ben-Zvi, Ruth; Eylon, Bat-Sheva; Silberstein, Judith
It is important to study the mental pictures of the atomic model formed by students at an early stage of their studies, since misunderstanding this model may prevent meaningful learning at later stages.

Chemical aspects of Bohr's 1913 theory Kragh, Helge
The chemical content of Bohr's 1913 theory has generally been neglected in the treatises on the history of chemistry; this paper regards Bohr as a theoretical chemist and discusses the chemical aspects of his atomic theory.
