(a) Name the scientist who gave this table.

(b) Which group of elements were not known at his time?

(c) This system worked quite well for the ………….. (heavier/lighter) elements.

(d) The table shown above relates the properties of the elements to their ………….. (atomic number / atomic mass)

(e) Why was this table discarded?

(a) John Newland

(b) 18th group of inert elements

(c) This system worked quite well for the lighter elements.

(d) The table shown above relates the properties of the elements to their atomic mass.

(e) Reasons for discarding the law of octaves:

1. This classification did not work for heavier elements i.e., those lying beyond calcium. As more and more of elements were discovered, they could not be fitted in this table.
2. Newland adjusted two elements cobalt (Co) and nickel (Ni) in the same slot and these were placed in the same column as fluorine, chlorine and bromine which have very different properties than these elements.
3. Iron, which resembles cobalt and nickle in properties, has been placed far away from these elements.
