Who gave the 'low of octoves '? Why it is called so ?
Answers
Answer:
In the year 1866, an English scientist, John Newlands arranged the elements in the order of increasing atomic masses. ... He noticed that every eighth element exhibits similar properties as compared to the first element. He called this law as the 'Law of Octaves' better known as 'Newland's Law of Octaves'
Explanation:
Law of octaves, in chemistry, the generalization made by the English chemist J.A.R. Newlands in 1865 that, if the chemical elements are arranged according to increasing atomic weight, those with similar physical and chemical properties occur after each interval of seven elements.
In the year 1866, an English scientist, John Newlands arranged the elements in the order of increasing atomic masses. Till then only 56 elements were known to us. He started with hydrogen which has the lowest atomic mass and finally ended at thorium which was the element known to have the highest atomic mass at that time. He noticed that every eighth element exhibits similar properties as compared to the first element. He called this law as the ‘Law of Octaves’ better known as ‘Newland’s Law of Octaves’. According to Newland’s Law of Octaves, as the observed properties of lithium and sodium are the same, sodium is placed at the eighth position with respect to lithium.

Defination of law of octaves:
Law of octaves, in chemistry, the generalization made by the English chemist J.A.R. Newlands in 1865 that, if the chemical elements are arranged according to increasing atomic weight, those with similar physical and chemical properties occur after each interval of seven elements. Newlands was one of the first to detect a periodic pattern in the properties of the elements and anticipated later developments of the periodic law.

atomic weight
Atomic weight, ratio of the average mass of a chemical element’s atoms to some standard. Since 1961 the standard unit of atomic mass has been one-twelfth the mass of an atom of the isotope carbon-12. An isotope is one of two or more species of…
