who discovered the periodic table?

Answer 1

Through scientific history, many different periodic tables were created, though none were "discovered." One of the most basic periodic tables was made by Aristotle, and his table contained the four basic elements - fire, water, earth, and air. As more knowledge about the earth and its elements was discovered, more detailed tables arose. Finally in 1869, two scientists, Dmitri Ivanovich Mendeleev and Julius Lothar Meyer, independently developed the periodic table we use today. Typically we credit Mendeleev with the creation because his primary calculations of atomic mass and other quantities were more accurate than Meyer's.

Answer 2

Just for the record, the Lawrence Berkeley National Laboratory retracted its paper on Element-118 in July of 2001. Element-116 and Element-114 are still unconfirmed. Element-112 is said to have a half life of 280 microseconds. Once one get above 83 protons (Bismuth), everything is radioactive and most isotopes are short lived. Mathematical model and practical experiments have both failed to find the "Plateau of stability" that was a common topic only 10 years ago. There are two different concepts to consider when looking at the possible advantages of larger atoms. The first is economics. Making these atoms is very expensive. The second is a matter of what new information can be learned. Most scientists in this field have come to the conclusion that they personally and scientifically are getting nothing for their efforts. Seeing the Periodic Table filling out is great. But as a chemist who has watched this process since about 1958, I can state that most of what has been added will not effect my chemistry or my life style. I suggest that you review those early papers and see why most other chemists would not support the physicists who would continue this process. No new element will save humanity. The appropriate uses of dwindling resources will be the driving force of any solution.

Answer 3

The periodic table of the chemical elements is a tabular method of displaying the chemical elements. Although earlier precursors exist, its invention is generally credited to Russian chemist Dmitri Mendeleev in 1869.

Answer 4

Mendeleyev did indeed "discover" the periodic table. He did not "invent" it, because he just ordered elements by their similar characteristics. However, Mendeleyev ordered the elements by atomic MASS rather than by atomic NUMBER, as the present periodic table is ordered.

Answer 5

Mendeleev not so much discovered it as devised it as a good way of tabulating elements

Answer 6

dimitri mendeleev invented it

Answer 7

it was not discovered
