Who was the first scientist to arrange the chemical elements in order of their atomic weights?
I believe it was Dmitri Mendeleev.
Who is the scientist discover and arrange the periodic tableof element?
The scientist usually recognised is the Russian Chemist and Engineer Dmitri Ivanovich Mendeleev in 1869. A German Chemist Julius Lothar Meyer published something similar in the same year. An English Chemist John Newlands published 2 versions of his 'Law of octaves' in 1863 and 1865. Both of his versions had (different) serious shortcomings, and were not recognised nor held in high regard at the time.
Why was Newlands and periodic table rejected?
John Newlands, in designing his table, believe that it was governed by the "Law of Octaves". While this is true for elements in what are now groups 2 and 3, it fails in period 4, when the periodicity becomes 18.
When was John Newlands - Australian politician - born?
John Newlands - Australian politician - was born in 1864.
When did John Newlands - Australian politician - die?
John Newlands - Australian politician - died in 1932.
When was John Alexander Reina Newlands born?
John Alexander Reina Newlands was born on 1837-11-26.
How many groups can the elements be put?
The elements are grouped in to 7's. I took John Newlands 12 years to think of that solution. :)
Who is John Newlands and Lothar Mayer and John Dalton?
They were all Chemists!:)
What was john newlands contribution to science?
he studided birds .....
Which scientist proposed the law of octaves?
John Newlands A+
What are john newlands triads?
John Dalton was the first person to begin ordering the elements. He did this according to atomic mass. John Newlands developed this idea further and noticed that there were similarities in ever eighth element, he called this "the law of octaves'. Newlands called each group (column) of three elements a 'triad'
How long did it take to make a piriodic table of elements?
British chemist, John Newlands had the idea of arranging chemical elements in order of their relative atomic masses and he arranged his elements in columns. However, Russian chemist, Dmitri Mendeleev greatly improved on Newlands' idea and convinced other chemists to use it, so Mendeleev has been credited with the invention of the periodic tbale...but as of today we are still developing some of hte last elements.... from: "http://inventors.about.com/library/inventors/blperiodictable.htm"
