who invited Newlands arrangement of Elements?
John Alexander Newland ( 1865 )
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'
Why was mendeleev better than john newlands?
mendeleev was better than john newlands because he gave all the elements systematical manner . he showed 80 elements except the noble gas and inert gas but newlands gave this but in improper manner because of this mendeleev was better
Who arranged elements using the law of octaves?
John Newlands (England) in 1865.
Who was the scientist who observed a pattern of properties that repeated every eight elements?
john newlands
How had john newlands previously tried to arrange the elements?
John Newland previously arranged the elements in the periodic table in order of relative atomic mass.
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"
Who was the first scientist to arrange the chemical elements in order of their atomic weights?
I believe it was Dmitri Mendeleev.
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. :)
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.
