This scientist was J. J. Thomson.
Julius Lothar Meyer was a contemporary of Mendeleev and like him and Newlands made contributions to the classification of elements in what we now call the periodic tabel.
Newlands and Dobereiner. Newlands did the Law of Octaves. Dobereiner did the Triads.
he studided birds .....
The Mendeleev table is more complex and rational.
The table of Newlands was only an incomplete precursor of the Mendeleev table.
Lavoisier, Dobereiner, Newlands, Mendeleev, and Moseley
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
Julius Lothar Meyer was a contemporary of Mendeleev and like him and Newlands made contributions to the classification of elements in what we now call the periodic tabel.
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.
Newlands and Dobereiner. Newlands did the Law of Octaves. Dobereiner did the Triads.
I believe it was Dmitri Mendeleev.

The Mendeleev table is more complex and rational.
The table of Newlands was only an incomplete precursor of the Mendeleev 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
Dimtrii Mendeleev made the first Periodic Table. dmitry mendeleev
