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 did Newlands arrange the elements in rows of seven?
Newlands arranged the elements in rows of seven to highlight a repeating pattern of chemical properties every eighth element, known as the Law of Octaves. This arrangement was an early attempt to organize the elements based on characteristics such as atomic mass.
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?
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.
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.
What is Newland's law of Octave?
what is newlands law of octaves
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.
Who developed the law of octaves?

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.
Why was the pattern that Newlands developed called the 'law of octaves'?
his tables contained gaps that elements with particular properties should fill.
How many groups did newlands periodic table have?
Newland arranged all the then known elements into seven groups in his 'law of octaves'
What was john newlands arrangement called?
John Newlands' arrangement of elements was called the "Law of Octaves." He proposed that when elements were arranged in order of increasing atomic mass, every eighth element exhibited similar properties, much like musical octaves. This early periodic classification highlighted the periodic nature of elements, laying the groundwork for the development of the modern periodic table.
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.
Which were the elements that didn't fit Newlands pattern?
Newlands' Law of Octaves, proposed by John Newlands in 1865, suggested that elements could be arranged in order of increasing atomic weight and that every eighth element would exhibit similar properties. However, this pattern did not hold true for all elements, particularly those with atomic weights greater than calcium, such as transition metals and heavier elements. Additionally, the arrangement did not accommodate the existence of noble gases, which were discovered later, and elements like iodine and tellurium, whose properties did not align with their positions in the octaves.
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.
