Answer 2

Answer:

An English scientist called John Newland's put forward his law of octaves in 1865. He arranged all the elements known at the time into a table in order of relative atomic mass.

He arranged the elements in increasing order of their atomic weights and noted that every eighth element had properties similar to the first element

But after atomic weight 40 d orbitals started which made 18 instead of 8 and then f orbital starts which makes it 32 other than 18.

Hence there is no organized division that's why it got failed.
