what is newlands law of octaves
The scientist who proposed the law of octaves was John Newlands in 1864. He noticed that when the elements were ordered by atomic weight, every eighth element had similar properties, similar to the musical concept of octaves.

John Newlands (England) in 1865.
Law of octaves was established by newland, before mandelleve. It states that : The properties of elements will repeat themselves after every 8th element. The series in which the elements were set was determined by newland. The law was not very successful because elements does not follow the same characteristics after mass no 40.
his tables contained gaps that elements with particular properties should fill.
Newlands Law of Octaves has many limitations, which are discussed below.1. This law was not applicable throughout the arrangement. It was applicable only till calcium.2. Newlands assumed that only 56 elements would exist in nature and believed that no more elements would be discovered. However, several elements were discovered in the following years. These elements did not follow the Law of Octaves.3. The positions of cobalt and nickel could not be explained according to Newlands Law of Octaves. He kept cobalt and nickel in the same slot. They were also placed in the same column as fluorine and chlorine, which have completely different properties.4. The properties of iron are similar to those of cobalt and nickel. However, iron was placed away from them in a different column.

Newland arranged all the then known elements into seven groups in his 'law of octaves'
