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 ✅✅.
