newland: he tried to see the periodicity of properties and stated his law of octaves as " When elements are arranged in the increasing order of their atomic weights every eight element has properties similar to their first" . He could arrange elements up to calcium only out of more than sixty elements then known.
doberneir: he grouped elements into triads. The atomic mass and properties of the middle element were mean of the other two. He could group only a few elements into triads. For example (1.) Li, Na and K (2.) Ca, Sr and Ba (3.) Cl, Br and I
