Which element were later discovered that filled in the gaps marked with an asterisk on his table?
The gaps marked with an asterisk on Dmitri Mendeleev's Periodic Table were later filled by the discovery of several elements, including gallium (Ga), germanium (Ge), and scandium (Sc). Mendeleev had predicted these elements' properties based on the patterns of the periodic table, and their eventual discovery in the late 19th and early 20th centuries confirmed his predictions. This success further validated the periodic law and the organization of elements by atomic weight and properties.
