Question

What were the limitations of Newlands law of octaves?

Answer 1

This law was applied only upto calcium After calcium every 8th element do not possess the same properties similar to that of the first.

Newland assumed that there were only 56 elements existed in nature and no more elements wold be discovered in the future.But later on several new elements were discovered.

One more drawback is that in order to fit elements into his table newlands adjusted two elements in the same slot and also put some unlike elements under the same column .

Answer 2

Hey there !!

$\bf \underline{ \implies Limitations \: of \: Newlands' \: law \: of \: Octaves .}$

→ Law of Octaves only applicable upto calcium and after calcium every 8th did not possess properties similar to that of the first.

→ At the time of Newlands' only 56 elements were existed in nature and Newlands'assume that no more elements will be discovered the future.

→ But, later on , several new elements were discovered, whose properties did not fit into the law of octaves.

→ One important demerit of Newlands' law that he adjusted two elements in the same slot such as Cobalt and nickel [ Co and Ni ] .

→ With the discovery of noble gases the law of octaves become irrelevant.

→ Newlands'law of Octaves worked well with lighter elements only.

✔✔ Hence, it is solved ✅✅.
