In brief....

Answer 1

newland law of octave = when elements are arranged in order of increasing atomic mass then they found that the property of 8th element was similar to that 1st elements

eg = the property of berylium has similar to sodium pro

Answer 2

Newlands law of octaves.In 1864,Newlands made an attempt to classify elements so he called this relationship as the Law of Octaves. according to Newlands law of Octaves when the elements are arranged in order of increasing atomic weights then every eighth element has properties similar to that of the first element.

For example :- let us take a row from newlands classification of elements. If we take the elements Li, Be, B, C, N,O, F and Na, lithium ( Li ) is the first element, and sodium is eight. It has been found that the properties of sodium are a repetition of the properties of lithium.

In short, Both lithium and sodium have similar chemical properties
