प्रश्न
Explain 'Newland's Law of Octaves.' Why was the law discarded?
उत्तर
Elements, when arranged in the increasing order of their atomic weights, are similar to the eighth and the first note of the musical scale. For example, the eighth element from lithium is sodium. Similarly, the eighth element from sodium is potassium. Thus, lithium and sodium provide any specific place for hydrogen.
This classification did not work with heavier elements.
Newland adjusted two elements Cobalt (Co) and Nickel (Ni) in the same slot.
Fe, which resembles Co and Ni in properties, has been placed far away.
