write the law of the new land low and his limitations
Answers
Answer:
The law of octaves states that every eighth element has similar properties when the elements are arranged in the increasing order of their atomic masses.
Limitations of Newlands’ Law of Octaves
The key shortcomings of Newland’s law of octaves are listed below.
Several elements were fit into the same slots in Newland’s periodic classification. For example, cobalt and nickel were placed in the same slot.
Elements with dissimilar properties were grouped together. For example, the halogens were grouped with some metals such as cobalt, nickel and platinum.
Newland’s law of octaves held true only for elements up to calcium. Elements with greater atomic masses could not be accommodated into octaves.
The elements that were discovered later could not be fit into the octave pattern. Therefore, this method of classifying elements did not leave any room for the discovery of new elements.
