In 1864, Newlands arranged the known 56 elements in the order of increasing atomic masses.
He observed that the properties of every eighth element are similar to the properties of the first element.
Based on this observation, he proposed the Law of Octaves for the classification of elements.
Law of Octaves: When the elements are arranged in the increasing order of their atomic masses, the properties of every eighth element are similar to the first.

Newlands' Law of Octaves Explained
Newlands' Law of Octaves was proposed by John Newlands in 1865, and it is significant in the development of the periodic table.
Arrangement of Elements
- Elements are arranged in order of increasing atomic mass.
- Newlands observed that when elements were listed according to their atomic mass, every eighth element exhibited similar properties.
Concept of Octaves
- The name "octaves" is derived from the musical scale, where every eighth note has a similar pitch.
- Similarly, Newlands proposed that elements show recurring properties after every eight elements.
Significance of Atomic Mass
- At the time, atomic mass was the most reliable way to classify elements, as the atomic number concept had not yet been established.
- This method helped highlight periodic trends in elemental properties, such as reactivity and physical characteristics.
Limitations
- While Newlands' Law of Octaves was groundbreaking, it had limitations.
- For instance, it did not accommodate the noble gases and some transition metals, which did not fit neatly into the pattern.
Conclusion
- Newlands' approach laid the groundwork for future periodic classification systems, leading to the development of the modern periodic table.
- Understanding this law is crucial for grasping the historical context of chemical classification and the evolution of the periodic table.
In summary, Newlands' Law of Octaves arranges elements by increasing atomic mass, demonstrating periodicity in elemental properties.
