disadvantage of newland's law of octaves:
#Newlands assumed that only 56 elements existed in nature and no more elements would be further discovered in the nearer future. But later on several new elements were discovered, whose properties couldn’t be defined as per the Law of Octaves.#In order to fit elements into law of octaves Newlands not only adjusted two elementsin the same slot but also adjusted some unlike elements under the same note.#Cobalt and nickel are in the same slot and are positioned in the same column with fluorine, chlorine and bromine possessing different properties than these elements.
Advantage of newland's law of octaves:
1. This law provided a basis for the classification of element into groups of elements having similar properties.
2. This law provided a wider scope to arrange all known elements into a tabular form

Answer:
English chemist J.A.R. Newlands in 1865 arranged the elements according to their increasing atomic weight. All the elements which show similar chemical and physical properties occur after an interval of 7 elements. This arrangement is known as the law of Octaves.
- Advantage-This law helped to arrange the elements with similar properties and provided a basis for classification.
- Disadvantage-This law is only applicable up to Calcium as only 56 elements existed at the time he made this law.
