John Newlands first published his "Law of Octaves" in 1863. It pointed out a recurrence of properties for every eighth element in a scheme involving just 21 of between 55 and 60 elements known at the tiime.
Two years later he presented to the Chemical Society in London a scheme that involved nearly all of the known elements. However he tried to 'force fit' elements into this scheme with little insight, and some of the family groupings are nonsensical.
Mendeleev's Periodic Law was published in 1869. His first Periodic Table that went with it at the time was followed by a revised version in 1871 which incorporated all known element, and left gaps for elements yet to be discovered.

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.
Who of these scientists Mendeleev J.J Thompson John Newlands and Lothar Meyer never made any contribution to the development of periodic table?
This scientist was J. J. Thomson.
Who are the Other scientists that arrange the periodic table?
Antoine-Laurent de Lavoisier and John Newlands were first to dicover the table but later the scientist named dimitri mendeleev full arranged the elements discovered at that time
Who invented the first periodic table arranged by mass?
Mendeleev created the first periodic table according to mass, although it was later changed by Moseley to be arranged by atomic number.
The scientist involved in the periodic table?
John newlands attempted to arrange the elements into the law of octaves but had got mocked by many peers
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.
Who designed the original periodic table?
A variety of people are claimed to have helped create the periodic table including Kekule and John Newlands, but the credit to how the Periodic Table currently looks (some gaps filled in by other chemists) typically goes to Mendeleev.
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.
What month was the periodic table created in?
August 20, 1864 was when John Alexander Reina Newlands produced the first periodic table of the elements.
Who are some of the people responsible for developing the Periodic Table of the Elements?
Henning Brand A.E. Beguyer de Chancourtious John Newlands Dimitri Mendeleeve
Which group is missing from john newlands periodic tabale?
pom
Who are the Scientists who contributed in the modern periodic table?
Dimitri Mendeleev produced the first periodic table leaving spaces for elements that were not yet known in 1869; Henry Mosely determined the atomic number of elements and corrected some inaccuracies in Mendeleev's periodic table.
Who of these scientists Mendeleev J.J Thompson John Newlands and Lothar Meyer never made any contribution to the development of periodic table?
This scientist was J. J. Thomson.
Who are the Other scientists that arrange the periodic table?
Antoine-Laurent de Lavoisier and John Newlands were first to dicover the table but later the scientist named dimitri mendeleev full arranged the elements discovered at that time
Who invented tables?
Lothar Meyer (1864) and John Newlands (1865) both proposed tables that organized elements according to periodic properties. History Most people think Mendeleev invented the modern periodic table.
Who invented the first periodic table arranged by mass?
Mendeleev created the first periodic table according to mass, although it was later changed by Moseley to be arranged by atomic number.
The scientist involved in the periodic table?
