Q.3. What were the limitations of Newlands’ Law of Octaves?
Answers (1)
The limitations of Newland's law of octaves are:
(1) It was found that the Law of Octaves was applicable only up to calcium, as after calcium every eighth element did not possess properties similar to that of the first.
(2) It was assumed by Newlands that only 56 elements existed in nature and no more elements would be discovered in the future. But, later on, several new elements were discovered, whose properties did not fit into the Law of Octaves.
(3) Newland put two elements together in one slot and that too in the column of unlike elements having different properties.
Example: Cobalt and Nickel were put together in just one slot and that too in the column of elements like fluorine, chlorine, and bromine which were very different properties from these elements.
