The Birth of the Idea of Atomism
John Dalton observed mathematical regularities with respect to the formation of a chemical compound. He concluded that the elements combined in fixed quantities, pointing toward the existence of atoms. […]

Atoms: The Structure of the Fundamental Units of Matter
John Dalton provided compelling evidence for the existence of atoms. However, atoms were not indivisible, as assumed. They have a complex structure, a structure built up from particles even smaller than atoms. […]

Discovering and Naming the Elements in Chemistry
For consistency, it is important that the names of the elements are same across different countries. To facilitate this, the IUPAC was formed in 1919. It has since set rules for naming the elements. […]

The Evolution of the Periodic Table
The periodic table of elements was first designed by Dmitry Mendeleev. Since then, many changes were introduced to the table as scientists continued to learn more about the elements. […]
