❇For the first time, it was shown that there is a distinct periodicity in the properties of elements. Demerits of Newland's Classification

↪ ❇This classification didn't work with heavier elements i.e. those lying beyond calcium

Answer 2

Answer:

hiii

Explanation:

MERITS :-

Newlands law of octave provided a basis for the classification of element on the basis of having similar properties into groups of elements. The arrangement of elements in tabular form was provided by Newlands law of Octaves. Newlands law of octave was the first logically basis on the atomic weight.

DEMERITS :-

Newland could arrange elements only up to calcium, out of the total 56 elements known. After calcium, every eighth element did not possess properties similar to that of the first. Only 56 elements were known at the time of Newlands, but later several elements were discovered.
