Examples: density, melting point, atomic weight, density and formula of oxide.
Mendeleev predicted the name "eka-aluminium" for the element that is now known as gallium. This naming convention was based on the positions of the elements in his periodic table.
The discovery of undiscovered elements with properties predicted by Mendeleev's periodic table (like gallium, germanium, and scandium) confirmed the accuracy of his organization. These elements filled gaps in the periodic table and established a pattern of periodicity that supported Mendeleev's initial insights.
Mendeleev predicted that gallium belonged to the R2O3. Gallium was not discovered until 1874. The noble gases weren't discovered until 1894 through 1899.
He predicted that elements with the predicted properties would be discovered to fill in these gaps.
Mendeleev predicted that gallium (Ga) would have properties of a metal based on its position in the periodic table. Gallium exhibits characteristics of a metal, such as being solid at room temperature, having a metallic luster, and conducting electricity.
Mendeleev predicted the existence and properties of gallium in his periodic table. He correctly anticipated that gallium would have a similar chemical behavior to aluminum and predicted its atomic mass, density, and melting point.
Examples: density, melting point, atomic weight, density and formula of oxide.

Mendeleev predicted the name "eka-aluminium" for the element that is now known as gallium. This naming convention was based on the positions of the elements in his periodic table.
The element discovered by Mendeleev in 1871 was germanium. Mendeleev predicted the existence of this element and its properties before it was actually discovered.
The discovery of undiscovered elements with properties predicted by Mendeleev's periodic table (like gallium, germanium, and scandium) confirmed the accuracy of his organization. These elements filled gaps in the periodic table and established a pattern of periodicity that supported Mendeleev's initial insights.
Mendeleev predicted that gallium belonged to the R2O3. Gallium was not discovered until 1874. The noble gases weren't discovered until 1894 through 1899.
He predicted that elements with the predicted properties would be discovered to fill in these gaps.
Mendeleev predicted the existence of elements like germanium, gallium, and scandium. He named them "eka-silicon," "eka-aluminum," and "eka-boron," respectively, based on their predicted properties in relation to the known elements at that time.
Mendeleev predicted the existence of eka-aluminum (later named gallium) in 1871 based on gaps in his periodic table. Four years later, in 1875, French chemist Paul-Émile Lecoq de Boisbaudran discovered gallium which had similar properties to the predicted eka-aluminum. This discovery validated Mendeleev's periodic table and his prediction methods.
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.
