Above, what is Newland law of octaves explain with example?
Newlands Law : When the elements are arranged in increasing order of their atomic masses, the properties of the eighth element are similar to that of the first. Examples : The eight element from lithium is sodium. ... Similarly, eight element from sodium is potassium.
Similarly, what is the law of octaves quizlet? Newland's law of octaves stated that elements properties repeated every eighth element. ... The statement that there is a periodic repetition of chemical and physical properties of elements when they arranged by increasing atomic number.
One way or the other, how many elements were there in Newland's law of octave?
Who gave the law of octaves?

The Newlands law of octaves states that when elements are arranged in the increasing order of atomic weights, every eighth element has similar properties to the first. In other words, the properties of elements are repeated after every seventh interval. ... The table below is from Newlands' publication of 1865.
“Dobereiner's Law of Triads deals with putting three elements in order of atomic weight. The average of the first and third elements' atomic masses is the atomic mass of the second element.
Answer: The major limitations of Newlands' law of octaves were : (i) It was applicable to only lighter elements having atomic masses upto 40 u, i.e., upto calcium. After calcium, the first and the eighth element did not have similar properties.
In devising his table, Mendeleev did not conform completely to the order of atomic mass. He swapped some elements around. ... He corrected the known atomic masses of some elements and he used the patterns in his table to predict the properties of the elements he thought must exist but had yet to be discovered.
The periodic law states “When elements are arranged in order of increasing atomic number, there is a periodic repetition of their chemical and physical properties.”
Features of Mendeleev's tables Mendeleev arranged the elements in order of increasing relative atomic mass . When he did this he noted that the chemical properties of the elements and their compounds showed a periodic trend .
The law failed because of the following reasons: 1 The law was applicable only upto calcium. It could not include the other elements beyond calcium. ii With the discovery of rare gases it was the ninth element and not the eighth element having similar chemical properties.
Regular repeats Newlands' table showed a repeating or periodic pattern of properties, but it had problems. For example, he put iron in the same group as oxygen and sulphur, which are two non-metals. As a result, his table was not accepted by other scientists.
Dobereiner could find only three triads; . i.e total of 9 elements only. However the total number of elements were more than that of those encompassed in Dobereiner's Triad. Thus, Dobereiner's could not be classify most of the elements known at that time.
repetition of the elements with similar properties after certain regular interval when atoms are arranged in increasing order of atomic number
is called periodicity
Such triads—including chlorine-bromine-iodine, calcium-strontium-barium, and sulfur-selenium-tellurium—were noted by the German chemist J.W. Döbereiner between 1817 and 1829. The triad was the earliest atomic-weight classification of the elements.
In 1869, Dmitri Mendeleev and Lothar Meyer individually came up with their own periodic law "when the elements are arranged in order of increasing atomic mass, certain sets of properties recur periodically." Meyer based his laws on the atomic volume (the atomic mass of an element divided by the density of its solid ...
