What is newlands law of octaves |
|
Answer» Newlands’ law of octaves\tIn 1866 an English scientist John Newlands arranged the elements in the order of\tincreasing atomic masses starting from the hydrogen having lowest atomic mass to the 56th element named thorium having the highest atomic mass among the elements discovered at that time.\tIt 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.\tThis was comparable to octaves found in music and hence was called the ‘Law of Octaves’ or ‘Newlands’ Law of Octaves’.\xa0\tBut the Law of Octaves was applicable only up to calcium, after which every eighth element did not resembled the first element. •newland arranged the non elements in the increasing order of atomic masses.•he started with hydrogen and ended with the 56th element thorium.•he also foynd that every 8th element had properties similar to the first one.•this was similar to the octaves found in music and he called it as law of octaves.Example: Barilium and Magnesium Lithium and sodium |
