Plzzz explain me about Newland\'s 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\xa0element 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. Thanks mr avi......?☺️?? Law of octaves, in chemistry, the generalization made by the English chemist J.A.R. Newlands in 1865 that, if the chemical elements are arranged according to increasing atomic weight, those with similar physical and chemical properties occur after each interval of seven elements ????❤️❣️? |
