John Newlands formulated the Law of Octaves in 1865. It states that if the chemical elements are arranged according to increasing atomic weight, the elements with similar physical and chemical properties occur after each interval of seven elements.

∙ 11y agoThe Octaves Law by John Newlands which was declared in 1864, can be stated as; 'When the elements are arranged in the order of increasing atomic weight, there'll be elements with chemically and physically similar properties seven elements apart, which is same as in musical scales'.
When his (modified) Periodic Table was submitted to the Chemical Society in London in 1865, and published in 1866, it was ridiculed and there were only three points of dismissive discussion. Although it was discarded by most of the scientists, Newlands was later awarded the Davy Medal in 1887, because of the importance of discovering periodicity.
Newlands' table contains 7 rows with roughly 8 elements per row.
Opinion of the original answerer:
There were inaccuracies in his table as some elements were not discovered in that time, but it was considerably identical to other classifications in that time period.
If he named his table by a different name, there might be a different situation.
Opinion of the revising answerer:
Newlands' original (1864) table recognised the same types of regularity as found in the more celebrated tables of Mendeleev and Lothar Meyer, but it only included 24 of nearly 60 known elements. His 1865-66 revision included 56 elements, but the classification of elements into families was greatly inferior and very questionable. His table was not nearly of the same quality as Mendeleev's, and there were quite valid reasons for the lack of recognition at the time of publication.

Notes on the edit:
(1) Atomic number was not discovered until Moseley's work in 1913
(2) Each 7th (not 8th) element will have similar (not identical) properties
(3) Submission date August 18 1865; publication date -- issue of March 9 1866.

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 groups did newlands periodic table have?
Newland arranged all the then known elements into seven groups in his 'law of octaves'
Why the law of octaves failed in classification of elements?
Newlands Law of Octaves has many limitations, which are discussed below.1. This law was not applicable throughout the arrangement. It was applicable only till calcium.2. Newlands assumed that only 56 elements would exist in nature and believed that no more elements would be discovered. However, several elements were discovered in the following years. These elements did not follow the Law of Octaves.3. The positions of cobalt and nickel could not be explained according to Newlands Law of Octaves. He kept cobalt and nickel in the same slot. They were also placed in the same column as fluorine and chlorine, which have completely different properties.4. The properties of iron are similar to those of cobalt and nickel. However, iron was placed away from them in a different column.
Why Did John Alexander Reina Newlands Study science?
John Alexander Reina Newlands studied science because he had a passion for understanding the natural world and wanted to contribute to scientific knowledge. He specifically focused on chemistry and developed the law of octaves, which was a significant contribution to the periodic table and the classification of elements. His work helped lay the foundation for further advancements in the field of chemistry.
What periodic trends did Mendeleev organize his periodic table by Atomic number Atomic mass Octaves Triads First ionization energy?
In 1869, Mendeleev organized his periodic table by increasing atomic mass (atomic weight), using what is called the "law of octaves," by which every 8th element in the sequence shared similar properties. This was first observed by John Newlands in his element table around 1863.
What is Newland's law of Octave?
what is newlands law of octaves
Which scientist proposed the law of octaves?
John Newlands A+
Who started the law of octaves?
by the English chemist J.A.R. Newlands in 1865
Who preceded Mendeleev and Meyer with work on the periodic table?
Newlands and Dobereiner. Newlands did the Law of Octaves. Dobereiner did the Triads.
Who arranged elements using the law of octaves?
John Newlands (England) in 1865.
Who developed the law of octaves?
Law of octaves was established by newland, before mandelleve. It states that : The properties of elements will repeat themselves after every 8th element. The series in which the elements were set was determined by newland. The law was not very successful because elements does not follow the same characteristics after mass no 40.
Why was the pattern that Newlands developed called the 'law of octaves'?
his tables contained gaps that elements with particular properties should fill.

What are john newlands triads?
John Dalton was the first person to begin ordering the elements. He did this according to atomic mass. John Newlands developed this idea further and noticed that there were similarities in ever eighth element, he called this "the law of octaves'. Newlands called each group (column) of three elements a 'triad'
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.
