Julius Lothar Meyer, a German chemist, played a crucial role in the development and understanding of the periodic table. His notable work included the independent development of a periodic classification of the chemical elements, similar to Dmitry Mendeleyev’s work. In his book “Die Modernen Theorien der Chemie,” published in 1864, Meyer presented a preliminary scheme for arranging elements based on atomic weight.
Meyer’s influential table, published in 1870, graphically displayed the periodic relationships of the elements, based on atomic volume and atomic number. Although Meyer did not claim priority for his achievement, his contributions to the periodic table and his exploration of atomic weight and properties of the elements laid foundations for modern science.

Meyer’s Periodic Table Contributions and Discoveries
Julius Lothar Meyer made significant contributions to the field of chemistry through his groundbreaking work on the periodic table. He focused on the classification and understanding of elements, bringing new insights into their atomic weight, chemical properties, and relationships based on atomic volume and atomic number.
Meyer’s contributions to the periodic table included recalculating atomic weights and utilizing the table to predict and study related elements’ chemical properties. His expanded table, published around 1868, visually demonstrated the periodic relationships of the elements, revealing patterns and trends that advanced the understanding of chemistry at the time.
In his exploration of atomic weight and properties of the elements, Meyer laid the foundations for modern science. His work provided a framework for future researchers to further investigate and uncover the mysteries of the elements, leading to remarkable advancements and discoveries in the field of chemistry.
The Impact of Meyer’s Work
Meyer’s periodic table contributions revolutionized the way scientists approached the study of elements. By recognizing the periodicity and relationships among elements, researchers gained invaluable tools for predicting and understanding the properties of both known and undiscovered elements.
This understanding enabled scientists to fill in the gaps in the periodic table, accurately predicting the existence and properties of elements that were not yet discovered. Meyer’s work paved the way for the development of a comprehensive and systematic arrangement of elements, forming the basis of modern chemistry.
|Atomic Number||Element||Atomic Weight||Atomic Volume||Chemical Properties|
|1||Hydrogen||1.00794||14.01||Highly reactive and flammable|
|6||Carbon||12.0107||5.42||Forms the basis of organic chemistry|
|20||Calcium||40.078||29.9||Essential for bone health|
|79||Gold||196.966569||10.21||Highly valued for its beauty and conductivity|
Meyer and Mendeleev’s Contributions to the Periodic Table
Julius Lothar Meyer and Dmitri Ivanovich Mendeleev both made significant contributions to the development of the periodic table during the same era, independently of each other. Inspired by Stanislao Cannizzaro’s presentation of Amedeo Avogadro’s hypothesis at the Karlsruhe Congress in 1860, both Meyer and Mendeleev sought to organize the elements in a systematic way.
Meyer’s textbook, “Die modernen Theorien der Chemie,” published in 1864, laid the foundation for his element arrangement. He classified the elements into families based on their atomic weights and valences. Mendeleev, on the other hand, published his textbook “Principles of Chemistry” in 1871. His work organized all known elements into a single table, following his discovery of the periodic law.
Both Meyer and Mendeleev recognized the periodic patterns among the elements and left gaps in their tables for undiscovered elements, accurately predicting their properties. These predictions were later proven to be correct when the predicted elements were discovered. Their contributions, along with their successful predictions, significantly advanced the field of chemistry and shaped the modern periodic table that we use today.
