Sir question number 6
Solution:
In 1864, Newlands made an attempt to classify elements. There are seven musical notes in music. Every eighth note is similar to the first one and it is the first note of the next scale. Similarly Newland stated that the eighth element starting from a given one is a kind of repetition of the first like the eight notes of an octave of music. So he called this relation ship as the Law of octaves.

So he called this relation ship as the Law of octaves.
According to Newlands' law of octaves when the elements are arranged in order of increasing atomic weights then every eighth element has properties similar to that of the first element.
In Newlands' table of elements, lithium, sodium and potassium occupied places near each other. Other similar elements like fluorine and chlorine or oxygen and sulphur were placed near each other. This classification worked well with the elements with small atomic weights but failed in the case of elements with large atomic weights.
He found that every eighth element had properties similar to that of the first. He compared this to the octaves found in music. This was love octaves found in music (SA,RE,GA,MA,PA,DHA,NI) and hence was called the ‘Law of Octaves’ or ‘Newlands’ Law of Octaves’.
