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.

What did John newlands do?
John NewlandsBorn: 26-Nov -1837Birthplace: London, EnglandDied: 29-Jul-1898Location of death: London, EnglandCause of death: InfluenzaJohn Newlands was an English chemist who pioneered the discovery of the periodic table of elements.He was one of the first, if not quite the first, to propound the conception of periodicity among the chemical elements. His earliest contribution to the question took the form of a letter published in the Chemical News in February 1863 Newlands arranged 62 elements of the elements known then in a table based on their atomic weight. He discovered that in his arrangement schematic, every eighth element displayed similar characteristics. He proposed, for the first time ever, the existence of periodicity as a property of the diffeHe was one of the first, if not quite the first, to propound the conception of periodicity among the chemical elements. His earliest contribution to the question took the form of a letter published in the Chemical News in February 1863rent elements.Based on his discovery reguarding every eighth displaying similar properties, he wrote a paper wherein he proposed the Law of Octaves, in 1863.The Law of Octaves stated that an element exhibits behavior that is similar to the eighth element preceding/succeeding it. He arranged all the elements known at the time into a table in order of relative atomic mass.
Classify the following statements regarding the law of conservation of mass as true or false It was developed from past observations?
True. The law of conservation of mass was developed based on past observations, experiments, and evidence that showed that mass is neither created nor destroyed in a chemical reaction.
Was there been more than one periodic table?
Yes, there have been several versions of the periodic table developed over time. The current version is based on Dmitri Mendeleev's layout, which arranges elements by their atomic number and chemical properties. Different scientists have made adjustments and improvements to the periodic table as new elements have been discovered.
According to Meyer what is the ratio with which sodium combines with oxygen?
Meyer's law of octaves states that elements combine to form compounds in simple whole number ratios. The ratio between sodium and oxygen in sodium oxide is 2:1, meaning that for every two atoms of sodium, there is one atom of oxygen.
Which scientist developed theories about flotation?
Archimedes, a Greek mathematician and physicist, developed the principle of buoyancy and is credited with the discovery of the law of flotation. His work in understanding the displacement of water by objects laid the foundation for our modern understanding of why objects float or sink in a fluid.
Why was the pattern that newlands developed called the law of octaves?
his tables contained gaps that elements with particular properties should fill.
Why was the pattern that Newlands developed called the 'law of octaves'?

What is Newland's law of Octave?
what is newlands law of octaves
Why was the pattern that newlands developed called the law of law of octaves?
his tables contained gaps that elements with particular properties should fill.
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.
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.
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.
When was the law of definite proportions developed?
The law of definite proportions was developed by Joseph Proust in 1806.
How many groups did newlands periodic table have?
Newland arranged all the then known elements into seven groups in his 'law of octaves'
How octaves does a bassoon have?
A bassoon can play 4 octaves.
How many octaves in 31 band eq?
31 octaves
