The periodic table is a tabular arrangement of the chemical elements, ordered by their atomic number, electron configurations, and recurring chemical properties.
Dobereiner's Law of Triads. Dobereiner, in 1817 suggested a relationship between the properties of elements and their atomic weights. Johann Wolfgang Dobereiner. According to Dobereiner, the atomic weight of the middle element is nearly the same as average of the atomic weights of other two elements.
