Today, many varieties of color-coded periodic tables exist. Subsequent chemists introduced additional color schemes to illustrate properties like electronegativity, electron configuration, and more. In the 1950s, American chemist Edgar Fahs Smith created one of the earliest color-coded periodic tables, using colors to categorize metals, nonmetals, and inert gases. The idea emerged in the 20th century as chemists looked for ways to better visualize the relationships between elements. History of Color Coding the Periodic TableĪlthough Dmitri Mendeleev is credited with creating the first periodic table in 1869, it did not originally contain any color coding. While the standard black-and-white version is familiar to most, color-coded periodic tables have become increasingly popular for visualizing different properties and trends of the elements.
