DOBEREINER (1815)

  • Arranged the elements in increasing order of their atomic weights, arranged into groups of three called triads.

NEWLAND (1864)

  • Arranged the elements in increasing order of their atomic weights, and suggested that in a given series - every eighth element was a repetition of the first.

MENDELEEFF (1869)

  • Arranged the elements in increasing order of their atomic weights in the form of table called periodic table and he observed that, elements with similar properties appear at regular intervals, this is called periodicity of properties of elements. He stated that properties of elements are periodic functions of their atomic weights.

MOSELEY (1912)

  • Arranged the elements in increasing order of their atomic numbers and he noticed that atomic number is a more fundamental characteristic of an element than its atomic weight. He stated that properties of elements are periodic functions of their atomic numbers. We all follow Moseley periodic table only.
