Interestingly, both Meyer and Mendeleev submitted papers on their periodic systems in 1869 to the German Chemical Society. While Mendeleev is widely credited with creating the first widely recognized periodic table, Meyer’s independent and systematic approach to organizing the elements provided crucial validation and refinement that helped solidify the periodic law as a fundamental principle of science.
Meyer Versus Mendeleev: Refining the Periodic Law Through Atomic Volume Curves
However, Newlands’ table was largely dismissed due to its forced grouping of elements and failure to accommodate newly discovered elements. He observed that when elements are arranged in order of increasing atomic weight, their atomic volumes increase in a regular, repeating pattern.
While Mendeleev is often celebrated for his bold predictions and advocacy, Meyer’s contribution lies in his precise, measurement-driven approach that helped prove the periodicity of the elements. Elements with similar chemical properties appeared at the peaks and troughs of these curves.

Accommodation of Anomalies: He was adept at explaining the placement of elements like cobalt and nickel, which have nearly identical atomic weights but vastly different properties, by emphasizing the periodicity of properties over strict atomic weight order. The subsequent discovery of gallium, scandium, and germanium validated the periodic law and, by extension, Meyer’s framework as a predictive tool.
