<P> Alexandre - Emile Béguyer de Chancourtois , a French geologist , was the first person to notice the periodicity of the elements -- similar elements occurring at regular intervals when they are ordered by their atomic weights . In 1862 he devised an early form of periodic table , which he named Vis tellurique ( the ' telluric helix ' ) , after the element tellurium , which fell near the center of his diagram . With the elements arranged in a spiral on a cylinder by order of increasing atomic weight , de Chancourtois saw that elements with similar properties lined up vertically . His 1863 publication included a chart ( which contained ions and compounds , in addition to elements ) , but his original paper in the Comptes Rendus de l'Académie des Sciences used geological rather than chemical terms and did not include a diagram . As a result , de Chancourtois ' ideas received little attention until after the work of Dmitri Mendeleev had been publicised . </P>
