The history of the periodic table reflects over two centuries of growth in the understanding of the chemical and physical properties of the elements, with major contributions made by Antoine-Laurent de Lavoisier, Johann Wolfgang Döbereiner, John Newlands, Julius Lothar Meyer, Dmitri Mendeleev, Glenn T. Seaborg, and others. [1][2] Early history.
Mendeleev discovered the periodic table (or Periodic System, as he called it) while attempting to organise the elements in February of 1869.
The periodic table was invented by Russian chemist Dmitri Mendeleev in 1869. However, prior to Mendeleev, chemists had been pondering for decades how to classify the elements. Beginning in 1789, Antoine Lavoisier began classifying elements by their properties.
Apr 2, 2014 · Russian chemist Dmitri Mendeleyev discovered the periodic law and created the periodic table of elements.
Oct 25, 2024 · Dmitri Mendeleev, Russian chemist who devised the periodic table of the elements. Mendeleev found that, when all the known chemical elements were arranged in order of increasing atomic weight, the resulting table displayed a recurring pattern, or periodicity, of properties within groups of elements.

Jul 5, 2022 · Mendeleev’s table ordered elements by increasing atomic weight and grouped them by recurring or “periodic” properties. The difference between his table and the modern table is that today’s periodic table lists elements by increasing atomic number (number of protons in the atom).
