Question

What were the limitations of Newland's law of octaves?

Answer 1

Limitations of Newlands' Law of Octaves ---
1) It was only applicable upto calcium, as after calcium every 8th element did not possess properties similar to 1st.
2) Newlands thought that only 56 elements existed and no more elements will be discovered. But, later on, several new elements were discovered that did not fit into Law of Octaves.
3) In order to fit elements in his table, Newlands adjusted 2 elements in the same slot but also put some unlike elements under same slot.
4) Newlands' law of Octaves worked only for lighter elements.

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 ✅✅.
