Who are the scientist and their contribution in development of periodic table?

Answer 1

.In 1869 the Russian chemistry professor Dmitri Ivanovich Mendeleev and four months later the German Julius Lothar Meyer independently developed the first Periodic Table, arranging the elements by mass. its invention though is generally credited to Russian chemist Dmitri Mendeleev . The layout of the table has been refined and extended over time, as new elements have been discovered. In the 1940s Glenn T. Seaborg identified the transuranic lanthanides and the actinides, which may be placed within the table, or below

Answer 2

The periodic table was originally conceived upon by Antoine Lavoisier. The periodic table now widely used was refined by Dmitri Ivanovich Mendeleev and is sometimes called "Mendeleev's Table".

Answer 3

Jean Baptiste Dumas, Leopold Gmelin, Ernst Lenssen, Max von Pettenkofer, and J.P. Cooke, John Newlands, A.E.Beguyer de Chancourtois, and there are many others who discovered and contributed the elements in the table periodic table... Some of the elements are named after its founder or the one who discovered it..

.. the one who made the PT was Lothar Meyer and Dmitri Mendeleev.. but Mendeleev was considered as the father of Periodic Table because his table became available to the scientific community before the table of Meyer's appeared.. :)

Answer 4

The Periodic Table was not something that was discovered. It is rather a organization of elements by their properties. The first scientist accredited with putting the periodic table together was Dmitri Mendeleev. He developed it in 1869 to illustrate periodic trends in the properties of the then-known elements; the layout has been refined and extended as new elements have been discovered and new theoretical models developed to explain chemical behavior. Mendeleev's presentation also predicted some properties of then-unknown elements expected to fill gaps in his arrangement; these predictions were proved right when those elements were discovered and found to have properties close to the predictions.

The periodic table has been changing the amount of elements since its creation, this table was elaborated to classify and distribute the chemical elements, based on their properties and characteristics. The invention of this table is due to the Russian, Dmitri Mendeleyev, a chemist from the University of St. Petersburg. While Dmitri published his periodic table in the year 1869, another chemist of German origin called, Julius Lothar Meyer, published another version a year later. At that time only about 60 elements were known within the natural, compared to the 112 that are known today. Both chemicals were based on some characteristics to be able to classify the elements, among them, that of placing the elements based on their atomic number.
