The modern periodic table has evolved through a long history of attempts by chemists to arrange the elements according to their reactivity and other properties as an aid in predicting chemical behavior. Now that we have arranged the table according to electronic structure, it makes sense to go back and look at earlier efforts in the light of what we know about electronic structure. One of the first to suggest such an arrangement was the German chemist Johannes Dobereiner — , who noticed that many of the known elements could be grouped in triads A set of three elements that have similar properties. Dobereiner proposed that all elements could be grouped in such triads, but subsequent attempts to expand his concept were unsuccessful. We now know that portions of the periodic table—the d block in particular—contain triads of elements with substantial similarities.

In , the Russian chemist Dmitri Mendeleev first proposed that the chemical elements exhibited a "periodicity of properties. What he found, however, was that the chemical and physical properties of the elements increased gradually and then suddenly changed at distinct steps, or periods. To account for these repeating trends, Mendeleev grouped the elements in a table that had both rows and columns. The modern periodic table of elements is based on Mendeleev's observations ; however, instead of being organized by atomic weight , the modern table is arranged by atomic number z. As one moves from left to right in a row of the periodic table, the properties of the elements gradually change.
