.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
Dmitri Mendeleev: Developed the Periodic Table in 1869, organizing elements by atomic weight and predicting new elements. Henry Moseley: Arranged elements by atomic number, leading to the modern periodic table. Glenn T. Seaborg: Proposed the actinide and transactinide series, expanding the periodic table to include more elements.
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".
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.. :)
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.
SCIENTISTS WHO CONTRIBUTED to the DEVELOPMENT OF PERIODIC TABLE ARE DMITRI MENDELEEV, JOHN DALTON, Johann Dobereiner, John Newlands, Julius Lothar Meyer, etc.
Russian chemistry professor Dmitri Ivanovich Mendeleevand Julius Lothar Meyer independently published their periodic tables in 1869 and 1870, respectively.

Who of these scientists Mendeleev J.J Thompson John Newlands and Lothar Meyer never made any contribution to the development of periodic table?
This scientist was J. J. Thomson.
What is the contribution of j j Thomson to the development of the periodic table?
JJ Thomson discovered the electron in 1897.
What is the contribution of de chancourtois?
De Chancourtois is known for his contribution to the development of the early periodic table of elements. He arranged the elements in a spiral or helical format based on atomic weights, which foreshadowed the modern periodic table structure. This arrangement helped in understanding the periodic trends and relationships between elements, paving the way for the organization of elements we use today.
Who is the scientist who recognized the periodic table for atomic number?
The scientist who recognized the periodic table for atomic number was Henry Moseley. He discovered that elements should be ordered by atomic number rather than atomic mass, which led to the modern understanding of the periodic table.
What is the contribution of Henry moseley in periodic tale of elements?
He found the number of protons an element has. present periodic table is according to it.
Who of these scientists Mendeleev J.J Thompson John Newlands and Lothar Meyer never made any contribution to the development of periodic table?
This scientist was J. J. Thomson.
What contribution did Mosley makers the development of the periodic table?
Henry Moseley showed elements in the periodic table should be in order by their atomic number instead of atomic mass.
Describe the contribution of early scientist in the development of periodic table?
Early scientists like Dmitri Mendeleev and Julius Lothar Meyer made contributions to the development of the periodic table by arranging elements based on their properties and atomic masses. Mendeleev's work led to the creation of the modern periodic table, which helped predict the properties of undiscovered elements and organize known elements in a systematic way. Meyer also made significant contributions by independently arranging elements in a periodic manner, which further supported the development of the periodic table.
What is the contribution of j j Thomson to the development of the periodic table?
JJ Thomson discovered the electron in 1897.
Which scientist is responsible for the Periodic Table?
Dmitri Mendeleev is credited with creating the Periodic Table of Elements in 1869. He arranged elements by increasing atomic weight and noticed periodic trends in their properties which led to the development of the modern periodic table.
Julius Lothar Meyer its contribution to the development of the periodic table?
Julius Lothar Meyer played a significant role in the development of the periodic table by independently publishing a periodic table of elements that showed the correlation between atomic volume and atomic weight. His work helped pave the way for the later development of the modern periodic table based on atomic number. Meyer's contribution, along with that of Dmitri Mendeleev, laid the foundation for our current understanding of the organization of elements.
What is the contribution of de chancourtois?
De Chancourtois is known for his contribution to the development of the early periodic table of elements. He arranged the elements in a spiral or helical format based on atomic weights, which foreshadowed the modern periodic table structure. This arrangement helped in understanding the periodic trends and relationships between elements, paving the way for the organization of elements we use today.
Which scientist discovered modren periodic table?
Moseley discovered the modern periodic table.
Who was the scientist that organized the elements into a table that you use today and what was the table called?
Dmitri Mendeleev organized the elements into the periodic table in the 19th century. His table is known as the Periodic Table of Elements.
What scientist created the periodic table?
Dmitri Mendeleev, a Russian scientist, is credited with creating the periodic table of elements in the 19th century. He arranged the elements in order of increasing atomic mass and grouped them based on their chemical properties, leading to the development of the modern periodic table.
What is the contribution of Dmitri mendeleev?
he invented the first periodic table..
What is dimitri mendeleev?
a scientist and the creator of the periodic table.
