Newlands published the "law of octaves" twice.
His first publication was not well regarded because it only included about 17 of the more than 60 elements known at the time.
After receiving this reaction, he had a second attempt, trying to fit in all known elements. This was "laughed out of court" at a meeting of the Royal Society because:
• the criteria for "chemical similarity" were not well defined nor consistent, leading to some quite bizarre groupings (a lot of obvious "force fitting").
• no allowance was made for possible new elements at a time when the rate of discovery of new elements was around 1 per year.
• the law did not arise out of any plausible theoretical treatment. It was purely empirical.
What else can I help you with?
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.
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.
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 are the defect of newland's law of octaves?
The main defect is that after the discovery of noble gas like neon, argon. After it the similar elements doesn't reoccur at the interval of eighth like that of eighth note of rhythm but occur at the interval of ninth which is against law.(dahal.ramchandra@gmail.com)
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?
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.
