lothar meyer chemie
He noticed a series of maxima and minima.
The table was divided into nine groups.
In the year 1882, both were jointly honored the Davy Medal by the Royal Society of London for their contributions to the periodic table.
When the chemical elements are thus arranged, there is a recurring pattern called the “periodic law” in their properties, in… Though originally educated as a physician, he was chiefly interested in chemistry and physics..
Physical science, the systematic study of the inorganic world, as distinct from the study of the organic world, which is the province of biological science. Both Mendeleev and Meyer worked with Robert Bunsen. Google is celebrating the 190th birthday of the chemist and writer Julius Lothar Meyer with a Doodle depicting him experimenting in the lab to a backdrop of his vertical display of elements.
Very nice, clear, and helpful.Informative article.
He worked on recalculating a number of atomic weights and made use of the
német kémikus.
It is surprising to note that both scientists were developing the same table and were completely unaware of each other's work for a considerable amount of time.
Meyer drafted his final version of the table in 1968. Lothar Meyer, (born Aug. 19, 1830, Varel, Oldenburg [Germany]—died April 11, 1895, Tübingen), German chemist who, independently of Dmitry Mendeleyev, developed a periodic classification of the chemical elements.
Thank you for the notes and charts!
This table was the transpose of his 1964's table, i.e., the rows were turned into columns and the columns into the rows.The above table is taken from Meyer's paper published in Julius Lothar Meyer was born to Friedrich Meyer, who was a physician, and Anna Biermann in Varel, Germany.
The most electropositive elements (Li, Na, K…) were observed at the peaks while the electronegative elements occurred at the ascent of the peaks.If we look at the above chart closely, all the elements between two consecutive maxima belong to the same period in the modern periodic table.
A kémia korszerű elmélete című művében (1864) már közölt egy 28 elemből álló táblázatot, amiben a csoportosítás még a vegyérték volt.

He completed his Ph.D. in chemistry in 1858.Meyer predicted the existence of undiscovered elements but did not elaborate on the properties of unknown elements, which Mendeleev did.
Julius Lothar Meyer (1830–1895) In 1862, he started working on his book Die modernen Theorien der Chemie, which described the first version of his periodic table. This is the primary reason why most people give the first credit to Mendeleev, not Meyer, for the development of the periodic table.
In 1864, he published the first version of his periodic table through his book From the previous table, it is clear that he not only ordered the elements with increasing atomic weights but also grouped them according to their valencies.
For example, Li, Be, B, C, N, O, and F are placed in period 2.

The trend in the chart depicts the periodicity of the elements.He published the finalized version of his periodic table in 1870.
He was one of the pioneers in developing the first periodic table of chemical elements.

Virtually any topic for the virtual learner.
Periodic table, in chemistry, the organized array of all the chemical elements in order of increasing atomic number—i.e., the total number of protons in the atomic nucleus.
The table was superior to any of its predecessors since it categorized the elements by their valencies.
For example, the elements of the first column—C, Si, Sn, Pb—combine with hydrogen to form tetrahydride—CHAlso, the empty slots in the table were an indication of the existence of undiscovered elements.Meyer plotted the graph of the atomic volume (molar volume) vs atomic weight.
In this table, he incorporated additional elements, particularly transition metals known at that time.
His early education was centered on pathology and medicine.
Julius Lothar Meyer, one of the scientists who pioneered the periodic table of elements, is celebrated in today's Google Doodle on what would have been his 190th birthday.
Our editors will review what you’ve submitted and determine whether to revise the article.Meyer worked in several areas of chemistry, but much of his activity grew out of his preoccupation with the classification of the elements. In 1859 Meyer began his career as a science educator, holding various …
Pályája, felfedezései. Peace.
Its government is headed by the chancellor (prime minister), who is elected by a majority vote of the Bundestag (Federal Assembly) upon nomination by the president (head of state).
