By placing the elements in order of their Atomic Mass then grouping them based on similar chemical properties, Mendeleev recognized that there were gaps in the pattern he made where elements should be. He predicted there were some elements yet to be discovered and predicted their chemical properties. The elements he predicted were later discovered and named germanium, gallium, and scandium.
Mendeleev ordered the elements according to increasing atomic mass in vertical and horizontal rows. The horizontal rows contained analogous elements. This system was clear and consistent, and was superior because the number of protons, the most massive particle in atoms, is actually what distinguishes each element.
Dmitri Mendeleev
Dmitri Mendeleev's periodic table allowed for the prediction of undiscovered elements based on the patterns of known elements. He arranged elements by increasing atomic mass and grouped them by similar chemical properties, which led him to leave gaps for elements he anticipated would be found later. For instance, he predicted the existence of gallium and germanium before they were discovered, as their properties aligned with the trends of elements in their respective groups. His periodic table's structure demonstrated that elements exhibit periodicity, enabling accurate predictions about their characteristics.
Dmitri Ivanovich Mendeleev was a Russian chemist and inventor. He is credited as being the creator of the first version of the periodic table of elements. Using the table, he predicted the properties of elements yet to be discovered.
Dmitri Mendeleev figured out that there were missing elements on his periodic table. Using periodic trends and averaging numbers, he could make pretty accurate predictions about elements not discovered yet. Mendeleev predicted four: * ekaboron (modern day scandium) * ekaaluminium (modern day gallium) * ekamanganese (modern day technetium) * ekasilicon (modern day germanium)

Dmitri Mendeleev published the first periodic table in 1869. He built on the work of several other scientists, including Antoine Lavoisier, Johann Dobereiner, Alexandre-Emile Beguyer de Chancourtois, and John Newlands, who had previously studied the best way to classify the elements.

This is a very wordy response, but by setting up the Periodic Table according to elements' properties and characteristics, he was able to predict any given elements' properties because, with the way the Periodic Table is arranged, all of the elements surrounding any specific element would have similar properties to the element that they surrounded. For example, at the time there was no element known as Aluminum, but given the properties of the elements around that area (Group 13), he was able to correctly predict Aluminum's properties. When aluminum was discovered, Mendeleev's predictions were extremely close to the actual element's properties.
