Answer 2

Answer:

• The attempt of Doberneir encouraged other chemist to correlate the properties of elements with atomic mass.

• In 1866, John newland and English scientist arranged the then known elements in the order of increasing atomic.

• He started with the element having the lowest atomic mass and ended with Thorium which was the 56th element.

• He found that every eight element had properties similar to that of first element.

• He compare this to the updates found in music therefore it is called law of octaves.

• In Newland's octave the properties of lithium and sodium were found to be same. Sodium is the eighth element after Lithium. Similarly beryllium and magnesium resemble each other.
