Newlands’ law of octaves

In 1866 an English scientist John Newlands arranged the elements in the order of
increasing atomic masses starting from the hydrogen having lowest atomic mass to the 56^th element named thorium having the highest atomic mass among the elements discovered at that time.
It was found that every eighth element possessed properties similar to that of the first. Sodium is the eighth element after Lithium possessing properties similar to one another. Similarly, beryllium and magnesium resemble each other.
This was comparable to octaves found in music and hence was called the ‘Law of Octaves’ or ‘Newlands’ Law of Octaves’.
But the Law of Octaves was applicable only up to calcium, after which every eighth element did not resembled the first element.
