Mendeleev organized the Periodic Table based on increasing Atomic Mass and grouped elements with similar chemical properties into columns. He left gaps for undiscovered elements, predicting their properties. Moseley later refined the table by arranging elements according to increasing atomic number, which resolved inconsistencies in Mendeleev's arrangement and established the modern periodic law that elements exhibit periodic properties when ordered by atomic number.

Moseley's periodic table?

Moseley's periodic table was developed by English physicist Henry Moseley in 1913. He rearranged the elements on the periodic table based on their atomic number rather than atomic mass, which led to the modern form of the periodic table. Moseley's work provided a clearer understanding of the organization of elements and their properties.
