Which of the following scientists provided the Law of Octaves?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. John Newlands.
The scientist who proposed the Law of Octaves was John Newlands. In 1864, Newlands introduced this concept as part of his work on the periodic table. The Law of Octaves suggests that elements, when arranged by increasing atomic weight, exhibit similar properties at intervals of every eighth element, akin to the musical octave. Although this law was an early attempt to organize elements and was later refined by other scientists, it laid important groundwork for the development of the modern periodic table.
