Newlands' Law of Octaves was rejected primarily because it was based on the observation of only 56 elements, which limited its applicability. While it successfully grouped elements with similar properties in the first few rows, it failed to accommodate new elements discovered later and did not apply well to heavier elements. Additionally, the law suggested that elements' properties repeat every eight elements, which was not universally accurate. This led to the development of the Periodic Table as a more comprehensive framework for organizing elements based on atomic number and properties.

Why was Newland's periodic table rejected?
The table of Newlands was only an incomplete precursor of the Mendeleev table.
Why did Newlands periodic table get rejected?
Newlands' periodic table, proposed in 1865, was rejected primarily because it was based on the law of octaves, which organized elements according to increasing atomic mass and recurring chemical properties every eight elements. This approach was too limited and did not accommodate new elements or variations in properties among elements within the same group. Additionally, it failed to account for the transition metals and did not recognize the need for a more systematic arrangement, leading to inconsistencies in the classification of elements. As a result, it was overshadowed by more comprehensive models, such as Mendeleev's periodic table.
How many groups did newlands periodic table have?
Newland arranged all the then known elements into seven groups in his 'law of octaves'
Why didnt helium and neon appear in Newlands table?
Helium and neon did not appear in Newlands' table because they are noble gases, which were not discovered until after Newlands' periodic table had been proposed. The noble gases were not known at the time when Newlands arranged the elements based on their properties.
Who was the scientist who observed a pattern of properties that repeated every eight elements?
The scientist who observed the pattern of properties that repeated every eight elements was John Newlands. He created the Law of Octaves, which grouped elements based on similar properties and noted the repetition every eighth element.
What is Newland's law of Octave?

Why was Newland's periodic table rejected?
The table of Newlands was only an incomplete precursor of the Mendeleev table.
Why was Newlands and periodic table rejected?
Newlands' periodic table was rejected because it had gaps and did not account for newly discovered elements. The periodic table was improved by Mendeleev's table, which arranged elements in order of increasing atomic weight and left gaps for undiscovered elements. This allowed for a more accurate prediction of the properties of missing elements.
Who started the law of octaves?
by the English chemist J.A.R. Newlands in 1865
Who arranged elements using the law of octaves?
John Newlands (England) in 1865.
Which scientist proposed the law of octaves?
The scientist who proposed the law of octaves was John Newlands in 1864. He noticed that when the elements were ordered by atomic weight, every eighth element had similar properties, similar to the musical concept of octaves.
What is the birth name of Scotty Newlands?
