Why didnt helium and neon appear in Newlands table?
Because they were not discovered and were unknown when Newlands proposed his periodic table
Why was Newland's periodic table rejected?
The table of Newlands was only an incomplete precursor of the Mendeleev 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 neon and helium missing from Newlands periodic table?
because inert gases were not discovered at that time..
How many groups did newlands periodic table have?
Newland arranged all the then known elements into seven groups in his 'law of octaves'

Why was Newland's periodic table rejected?

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 preceded Mendeleev and Meyer with work on the periodic table?
Newlands and Dobereiner. Newlands did the Law of Octaves. Dobereiner did the Triads.
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.
Table of periodic elements?
See the link below fot the IUPAC model of the periodic table of elements.
