Dmitri Mendeleev is credited with our current periodic table. Even predicted the existence of elements that were not yet discovered(i.e. Gallium). What is the periodic table?. periodic- a regular repeating pattern. periodic table- arrangement of elements so that their physical and chemical properties follow a regular repeating pattern. Rows and columns. Section 1. Development of the Modern Periodic Table. The periodic table evolved over time as scientists discovered more useful ways to compare and organize the elements.. Section 1: . Development of the Modern Periodic Table. Classification of Elements. 1829 German Chemist J.W. . Dobereiner. published a classification system to sort elements.
