Periodic Table

    :frown:

    Hello, guys. I need help. My professor ask us to search for the 20 scientists who prepared the Periodic Table. Well, so far, I only found 10 scientists.

    1.Aristotle
    2.Antoine Lavoisier
    3.Jöns Jakob Berzelius
    4.Johann Döbereiner
    5.John Newlands
    6.Lothar Meyer
    7.Dmitri Mendeleev
    8.William Ramsay
    9.Henry Moseley
    10.Glenn Seaborg

    but I'm not sure...

    Well, anyway, can you give me the names of the 20 scientists who prepared the Periodic Table? Thanks :smile:

    I would add Joseph Priestley and John Dalton , both 18C British chemists

    John Dalton has probably the best claim to inventing the periodic table and Mendeleev to refining it.

    There aren't 20 scientists that created the periodic table - it's not like there was a committee that sat down and invented it.
    The ideas behind it were developed over 2500 years from greek philosophy about atoms to quantum mechanics.

    I think one would have to look at the understanding of the elements and their periodicity (or chemical similarity) before and after Mendeleev developed his version of the periodic table.

    Google: "Dmitri Mendeleev","Periodic Table" - and see what is available.

    For example - http://www.aip.org/history/curie/periodic.htm

    or - http://www.rsc.org/education/teachers/learnnet/periodictable/pre16/develop/mendeleev.htm - where one will find

    Rather than scientists who created the periodic table (other than those like Mendeleev), I think one is looking for scientists who discovered elements and contributed either to the development of the periodic table (e.g. before Mendeleev) and those who filled in the holes.

    One can also read about elements and their history at www.webelements.com . Under the history of technetium, one finds "Technetium was discovered by Carlo Perrier, Emilio Segre at 1937 in Italy."

    Have you followed link I posted? Mark (owner of the metha-synthesis) has quite a collection of periodic tables of different shapes and forms, starting from ancient Greek, ending in modern times.
