Discovery of Gallium Validated Periodic Table, Sparking Debate Among Chemists

Chennai, India – November 22, 2025 – The Hindu’s e-Paper edition today delved into the fascinating history of gallium’s discovery and its crucial role in solidifying the acceptance of the periodic table. The article highlights the contributions of not only Dmitri Mendeleev, but also Lothar Meyer and Paul-Emile Lecoq de Boisbaudran.

Published in the “Science For All” section, the piece chronicles the parallel efforts of several 19th-century chemists to organize elements by their properties. While Mendeleev is widely credited with the periodic table’s creation, the story emphasizes that Meyer also devised a periodic table.

The discovery of Gallium by de Boisbaudran in 1875 provided the scientific breakthrough to proving that the periodic table was legitimate. Even though de Boisbaudran was initially skeptical of Mendeleev, his later finding of gallium’s features closely resembled what Mendeleev originally predicted in his own periodic table.

Following Meyer’s death in 1895, Mendeleev sought recognition for his work and claiming that the use of predicitons was a crucial differentiator for his work. However, he was only jointly recognized, as Meyer also had major contributions to the creation of the periodic table.

The article dives deeper into the naming of the element gallium. De Boisbaudran named it after his home country of France, but also received accusations for naming it after his own family name “Le coq.”

This illuminating article seeks to ensure credit is shared among the chemists, and their dedication to their field is what made the periodic table what it is today.
