Question
Explain 'Newland's Law of Octaves.' Why was the law discarded?
Solution
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.
