periodic table

a systematic arrangement of the chemical elements. An earlier version was devised in 1869 by Dmitri Ivanovich Mendeleev (Russian chemist, 1834-1907). By arranging the elements in order of their atomic weights, he was able to show relationships, such as valency, that occurred at regular intervals and was able to predict the properties of elements still undiscovered in the nineteenth century.
