Which Royal Society medal did Mendeleev receive in 1905? The Copley Medal.

The Royal Society awarded Dmitri Mendeleev its Copley Medal in 1905, recognizing the importance of his chemical research and his development of the periodic table. The Copley Medal is one of the Royal Society's oldest and most prestigious scientific awards.

Mendeleev had already received another major Royal Society honor: the Davy Medal in 1882. That earlier award is a common source of confusion, but it was not the medal presented to him in 1905. The later award was specifically the Copley Medal.

By 1905, Mendeleev's reputation rested not only on arranging known elements but also on predicting undiscovered ones. The later discoveries of gallium, scandium, and germanium broadly matched his forecasts and strengthened the case for periodic organization.

The Copley Medal joined a long list of international honors. Mendeleev remained scientifically active across chemistry and related fields until his death in 1907, two years after receiving the medal.
