Concept explainers
Interpretation:
The contribution of Newland’s law of octaves to the development of the modern periodic table needs to be explained.
Concept introduction:
In 1866, John Newlands proposed the law of octaves which states that in arranging elements in order of increasing atomic masses, every eighth element possesses properties similar to the first.

Answer to Problem 26A
Newland’s law of octaves gives the idea of repetitive pattern of the periodic table.
Explanation of Solution
Newland’s law of octaves was the first which shows the repeating pattern in terms of the properties of elements. This law is based on arrangements of elements considering their
Our periodic table is a periodic function of the atomic numbers. Newland’s law of octaves was the first to bring the idea of repetitive nature.
