Read Explanation:
• John Newlands proposed his Law of Octaves in 1865, arranging known elements in order of increasing atomic weight.
• He observed that every eighth element, when arranged this way, showed similar physical and chemical properties to the first element in that series. This was analogous to the octave in music.
