Merits:

(i) This classification worked well for lighter elements only up to Ca.

(ii) This classification gave us a relation between the properties of the elements and their atomic masses.(iii) It was shown by this classification for the first time that there exists a periodicity in the properties of the elements.

Hope it helps you.!!

Answer 2

Explanation:

Newland's Law of Octaves

• An English chemist, John Alexander Newlands in 1865 made an attempt to classify the elements knownin the increasing order of their atomic masses known as law of octaves. He noticed that the every eighth element of the series has properties similar to the first element as every note resembles the first in octave of music. It means that after a difference of seven elements, the element with similar characteristics was observed.
