Answer 1

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.

Answer 2

$\huge\bold\blue{Answer}$

According to the Newlands' law of octaves, when elements are arranged in the order of increasing atomic masses, the properties of the eighth element (starting from a given element) are a repetition of the properties of the first element.

For example: If we start with lithium as the first element, we find that the eighth element from it is sodium having the similar properties to lithium.⠀⠀⠀⠀⠀⠀⠀⠀⠀
