What is the difference between the discoveries of Mendeleev and Moseley?
The difference between Mendeleev and Moseley periodic table is that Mendeleev periodic table is created based on the atomic masses of chemical elements whereas Moseley periodic table is created based on the atomic numbers of chemical elements.
What are the main differences between Newlands and Mendeleev’s periodic table?
Similarities and differences
| Newlands | Mendeleev |
|---|---|
| Included only the elements known at the time | Left gaps for elements he predicted would be discovered later |
| Maintained a strict order of atomic weights | Swapped the order of some elements if that fitted their properties better |
What are the differences in the periodic tables as proposed by Meyer and Mendeleev?
Mendeleev created the first periodic table and was shortly followed by Meyer. They both arranged the elements by their mass and proposed that certain properties periodically reoccur. Meyer formed his periodic law based on the atomic volume or molar volume, which is the atomic mass divided by the density in solid form.
What is the difference between Mendeleev and modern periodic table?
This law modifies the Mendeleev’s periodic table into the Modern periodic table….Complete step by step solution:
| Mendeleev’s periodic table | Modern periodic table |
|---|---|
| Elements are arranged based on their increasing in atomic mass | Elements are arranged based on the increasing order of their atomic numbers. |
Why did scientists disagree with Mendeleev’s table?
One of the reasons Newland’s table was not accepted was that he had many more dissimilar elements in a column whereas Mendeleev left gaps for undiscovered elements. Mendeleev also predicted the properties of missing elements, which were later discovered, fitting the gaps and matching the predicted properties.
Why is Mendeleev’s table better than Newlands?
Mendeleev left gaps if necessary whereas Newland only included the elements known at the time. Mendeleev’s was more flexible as he swapped the positions of elements if that suited their properties better, whereas Newland maintained a strict order of atomic mass.

What was Lothar Meyer famous?
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.
Why is Julius Lothar Meyer important?
Julius Lothar Meyer (19 August 1830 – 11 April 1895) was a German chemist. He was one of the pioneers in developing the earliest versions of the periodic table of the chemical elements.
What is the basic difference in approach between Mendeleev?
Solution 2 The basic difference in approach between Mendeleev’s Periodic Law and Modem Periodic Law is the change in basis of classification of elements from atomic weight to atomic number.
How did Mendeleev’s periodic table differ from Meyers?
This 1868 table listed the elements in order of atomic weight, with elements with the same valency arranged in vertical lines, strikingly similar to Mendeleev’s table. Unfortunately for Meyer, his work wasn’t published until 1870, a year after Mendeleev’s periodic table had been published.
How did Julius Lothar Meyer differ from Dmitri Mendeleev?
Whereas Meyer continued to pursue a life of research and teaching and spent the last 20 years of his life as a professor at Tübingen, Mendeleev’s strong democratic leanings got him into trouble with political and academic authorities, although his scientific eminence and the usefulness of his advice protected him to a certain degree.
What did Dmitri Ivanovich Mendeleev do for a living?
His early contacts with political exiles gave him a lifelong love of liberal causes, and his freedom to roam the glassworks stimulated an interest in business and industrial chemistry. His mother—after her husband’s death and shortly before her own—took the 15-year-old Dmitri to St. Petersburg.
How did Martin Meyer contribute to the periodic table?
Meyer did contribute to the development of the periodic table in another way though. He was the first person to recognise the periodic trends in the properties of elements, and the graph shows the pattern he saw in the atomic volume of an element plotted against its atomic weight.
