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'

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

John Newland previously arranged the elements in the periodic table in order of relative atomic mass.
I believe it was Dmitri Mendeleev.
The elements are grouped in to 7's. I took John Newlands 12 years to think of that solution. :)
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.
