The development of the periodic table began with early attempts to classify elements, such as Antoine Lavoisier's distinction between metals and non-metals. Dmitri Mendeleev is widely credited with creating the first widely accepted periodic table in 1869, arranging elements by increasing atomic mass and predicting the existence and properties of undiscovered elements. Later, Henry Moseley refined the table in 1913 by arranging elements by increasing atomic number, which resolved inconsistencies found in Mendeleev's original arrangement.
