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]
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.
Discover the key scientists behind the periodic table including Dmitri Mendeleev, Henry Moseley and John Newlands in the Royal Society of Chemistry's Visual Elements Periodic Table.
150 years ago, Russian chemist Dmitrii Mendeleev created the periodic table of the elements, revolutionizing chemistry.
These versions were relatively simple though and were also somewhat obscure and hard to read. The scientist who brought it all together was Dmitri Mendeleev (1834 to 1907). Mendeleev was a Russian born chemist and the first to publish a modern version of the periodic table. His table ordered the elements by atomic weights (molar masses).
For both Meyer and Mendeleev, writing a textbook proved to be the impetus for developing the periodic table—a device to present the more than 60 elements known at the time in an intelligible fashion. Today’s instantly recognizable table includes well over 100 elements.
Periodic table, in chemistry, the organized array of all the chemical elements in order of increasing atomic number. When the elements are thus arranged, there is a recurring pattern called the ‘periodic law’ in their properties, in which elements in the same column (group) have similar properties.
The “short-period” form of the periodic table, with Groups 0, I, II,…VIII, became popular and remained in general use until about 1930. Based on an earlier (1882) model of T. Bayley, J. Thomsen in 1895 devised a new table.
The first recorded attempt at creating a system to organise the elements was when Antoine Lavoisier published his table of elements in 1789. In 'Traite Elementaire de Chimie', Lavoisier listed 33 substances he considered elements, including light and caloric (heat).
Chemists generally credit Dmitri Mendeleev for inventing the periodic table that led to the modern version. If you ask a chemist who invented the periodic table, the usual answer is Russian chemist Dmitri Mendeleev in 1869. His table most closely resembles the modern periodic table.
