How did he arrange his periodic table
WebMendeleev began his work on the periodic table by collecting all of the known elements and organizing them according to their atomic weights (the mass of an atom relative to that of carbon-12). He then noticed that certain elements had similar chemical properties and arranged them in vertical columns in his table. http://api.3m.com/how+did+mendeleev+arrange+the+periodic+table

WebJohn Dalton did not arrange the periodic table. However, he brought in his atomic theory which had five postulates that are still valid. With this development, it became clear that Mendeleev has arranged the periodic table in order of increasing atomic number. This helped the chemists in discovery of new elements. Thank Writer Blurt WebOn 17 February 1869, Russian chemist Dmitri Mendeleev jotted down the symbols for the chemical elements, putting them in order according to their atomic weights and inventing the periodic table.He ...
WebMendeleev arranged the elements in his periodic table ordered by atomic weight or mass. He arranged the elements in periods and groups in order of their increasing atomic weight. He placed the elements with similar properties in the same group. However, he did not stick to this arrangement for long. WebThe periodic table of the elements is arranged according to the number of protons in the nucleus of the atoms. By starting each row with an element that contains a single …
WebHenry Moseley, in full Henry Gwyn Jeffreys Moseley, (born November 23, 1887, Weymouth, Dorset, England—died August 10, 1915, Gallipoli, Turkey), English physicist who experimentally demonstrated that the major properties of an element are determined by the atomic number, not by the atomic weight, and firmly established the relationship …
