how keen the film-makers were on understanding precisely how Mendeleev arrived at his famous first periodic table of 1869. This in turn meant that I had to thoroughly review the literature on this particular historical episode‚ which will form the basis of this blog. 2. The usual version of how Mendeleev arrived at his discovery goes something like this. While in the process of writing his textbook‚ The Principles of Chemistry‚ Mendeleev completed the book by dealing with only eight of the then known

information from different perspectives paves the way for progress because it allows for the same information to be seen from different views to allow more ideas about the information‚ like in the case of Aristotle vs. Lavoisier and the case of Mendeleev and the periodic table. First of all‚ people change their mind to find a better common ground that is more truthful and correct because of several different perspectives put together.

Atomic theory is the idea that matter is made up of small particles made of atoms. The atomic theory first had 5 points which were stated by John Dalton who came up with it. The first one was that all elements were made up of small units called atoms. The second one was that all atoms of a given element are identical to each other. Third‚ all the atoms were different from all the other atoms. Fourth‚ atoms of different elements combined together in equal numbers to form compounds. Fifth and final

Within the table‚ elements with similar Mass are placed together in groups. Like other chemists‚ such as Newlands‚ Mendeleev listed elements in order of Properties but he realised that he need to leave Gaps for elements that had not yet been Discovered.

and created the first geometrical representation of the periodic table. John Newlands proposed the Law of Octaves which states the elements repeat the chemical properties after every eighth element. Lothar Meyer and Demetriv Mendeleev published their own periodic table. Mendeleev arranged the elements in order of increasing atomic weight and grouped the elements of similar properties together. William Ramsay and Lord Rayleigh discovered the noble gases‚ which were added to the periodic table as group
