Question

What are the classification of newlands law of octaves?

Answer 1

Explanation:

Newlands law of octaves

In the in the year 1864, the British chemist John newlands attempted the 62 elements known at that time. He arranged them in ascending order based on their atomic masses and observed that every eighth element have similar properties. On the basis of this observation, Newland 's law of octaves was formulated.

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. Newland compare the similarities between the elements to the octaves of the music, where every eighth note is comparable to the first. This was the first attempt at assigning an atomic number to each element. However, this method of classifying elements was met with a lot of resistance in the scientific community.

Answer 2

Newlands' law of Octaves:

1. John Newlands was a British chemist. Newlands (1865) found that when elements were arranged in the ascending order of their atomic weights they appeared to fall into seven groups.

2. Each groupcontained elements with similar chemical properties.

3.Based on these observations, Newlands proposed the law of octaves.

4.The law of octaves states that when elements are arranged in the ascending order of their atomic weights they fall into a pattern in which their properties repeat at regular intervals.

5.Every eighth element starting from a given element resembles in its properties to that of the starting element.
