Answer to Question #21617 in Inorganic Chemistry for FOLUSO OLOMOSOLA
WHICH SCIENTIST TRIED CLASSIFYING ELEMENTS INTO PERIODS
Dmitri Ivanovich Mendeleev in 1869& create the periodic tables of elements, . in it he attempted to classify the elements according to their chemical properties.& Before it& other scientists had previously identified periodicity of elements. For example, John Newlands described a “Law of Octaves”, noting their periodicity according to relative atomic weight in 1864, publishing it in 1865. His proposal identified the potential for new elements such as germanium. Another person to prose a periodic table was Lothar Meyer, who published a paper in 1864 describing 28 elements classified by their valence, but with no prediction of new elements.
I appreciate the site services immensely, and it serves the purpose for what I need. However, honest feedback, I do find some of the college level writing less than adequate. The word's usage being weak and not very succinct thesis's or formatting seemed something I'd have to go back through the assignment and fix. That said, highly recommend still.
