Question

limitations of newlands periodic table​

Answer 1

Answer:

Limitations of Newland's Law of Octaves:

Newland could arrange elements only up to calcium, out of the total 56 elements known.

After calcium, every eighth element did not possess properties similar to that of the first.

Only 56 elements were known at the time of Newlands, but later several elements were discovered.

Hope it helps. Jai Shri Krishna

Answer 2

Answer:

The major limitations of Newlands' law of octaves are-

It was applicable to only lighter elements having atomic masses upto 40u, i.e., upto calcium. After calcium, the first and the eighth element did not have similar properties.

Those elements that were discovered after Newland's octaves did not follow the law of octaves.

Some similar elements have been separated from one another while some dissimilar elements have been placed in the same column.
