Newlands Law of Octaves

Newlands’ Law of Octaves

  • He arranged the elements according to the increasing order of atomic mass.
  • He found that every eighth element had properties similar to that of the first. He compared this to the octaves found in music. Therefore, he called it the ‘Law of Octaves’.


  • It was found that the Law of Octaves was applicable only up to calcium, as after calcium every eighth element did not possess properties similar to that of the first.
  • It was assumed by Newlands that only 56 elements existed in nature and no more elements would be discovered in the future.
  • Cobalt and nickel are in the same slot and these are placed in the same column as fluorine, chlorine, and bromine which have very different properties than these elements. 
  • Iron, which resembles cobalt and nickel in properties, has been placed far away from these elements.
