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.

Why was John Alexander Reina Newlands periodic table rejected?
Newland's Periodic Table was rejected because it had errors, for example he put iron and oxygen and sulfur in the same group even though iron is a metal and the other two are non-metals. This, along with the fact he put elements such as cobalt and nickel in the same box, made his table unacceptable.
How were the elements arranged on his periodic table?
newlands arranged the elements in the periodic table in order of relative atomic massNewlands arranged elements in group of eight like musical notes.
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.
Which group is missing from john newlands periodic tabale?
pom
Which scientist developed the only periodic table of elements?
Dmitri Mendeleev published the first periodic table in 1869. He built on the work of several other scientists, including Antoine Lavoisier, Johann Dobereiner, Alexandre-Emile Beguyer de Chancourtois, and John Newlands, who had previously studied the best way to classify the elements.
Why was Newland's periodic table rejected?
The table of Newlands was only an incomplete precursor of the Mendeleev table.
What was wrong with newlands periodic table?
it wasn't a real table
Why didnt helium and neon appear in Newlands table?
Because they were not discovered and were unknown when Newlands proposed his periodic table
Who preceded Mendeleev and Meyer with work on the periodic table?
Newlands and Dobereiner. Newlands did the Law of Octaves. Dobereiner did the Triads.
Why was John Alexander Reina Newlands periodic table rejected?

How many elements had they discovered in 1865 when Newlands was developing the Periodic Table?
62
Why was neon and helium missing from Newlands periodic table?
because inert gases were not discovered at that time..
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.
What is the correct chronological order of scientists contributing to the modern periodic table?
Lavoisier, Dobereiner, Newlands, Mendeleev, and Moseley
How were the elements arranged on his periodic table?
newlands arranged the elements in the periodic table in order of relative atomic massNewlands arranged elements in group of eight like musical notes.
How many groups did newlands periodic table have?
Newland arranged all the then known elements into seven groups in his 'law of octaves'
How was it hard to decide the periodic table?
Many attempts were made by Dobereiner , Newlands and Mendeleev in initial stages. Later on , the idea of arranging elements in increasing atomic number came up which is the today's periodic table.
