(plz answer in 3 - 4 mark)

Answer 1

What were the achievements of Newlands' Law of Octaves?



In Newland's periodic table, each row of elements consists of a total of seven elements and the eighth element falls under the first element. In the first column Lithium is the first element and sodium is the eighth element. Similarly, the eighth element after sodium is potassium. Hence from Newland's law of octaves, the elements Li, Na and K must have similar chemical and physical properties, and they do.

In the second column, Beryllium (Be) is the first element and Magnesium (Mg) is the eighth one. After magnesium the next eighth elements is calcium (Ca). Hence according to Newland's law, these elements should show similar chemical and physical properties.

In another vertical column with carbon (C) as the first element, the eighth element is silicon (Si). Both C and Si also show similar properties. Both are non-metals and show tetravalency. Thus Newland's law of octaves holds good for all these given columns. Similarly, the last group of halogens, from fluorine (F) to chlorine (Cl) also show similarity in their properties.

Answer 2

Hey there!!

There were not so achievement
some of his achievement are as follow -

He arranged the known elements in the order of increasing atomic masses and found that every eight element had properties similar to that of the first he compared this to the octaves found in music, that is SA , RE , GA , MA , PA , DHA , NI , and the west , they use the notations - Do ,re ,mi , fa ,so, la ,ti

and hence he called it the law of octaves

Hope this helps u !!
