Answer:
Newlands' law was applicable only till calcium, after Ca, every eighth element did not possess properties similar to first. ... Wrong order of arrangement of elements was done, e.g. Co and Ni do not resemble halogen were found together in same slot, Fe being similar to Co and Ni was separated and kept in different slot.
