Only some elements were discovered during the life of Mendeleev.
He realized that some elements had not been discovered.
Yes, Dimitri Mendeleev did (accurately, I might add) predict where elements would appear in his table. He also correctly predicted some of the missing elements' properties, based on where they were positioned in his table.
Dmitri Mendeleev created the periodic table to organize and classify the known elements based on their properties and atomic weights. He left gaps for undiscovered elements and successfully predicted the properties of some of these missing elements.

some guy called Mendeleev
the large gaps
He realized that some elements had not been discovered.
When making his periodic table Mendeleev noticed some spaces where elements should be couldn't be filled. He didn't want to force elements that didn't belong there to go there, so he believed the spaces were undiscovered elements. He left the names blank but predicted their properties. Later the elements Mendeleev predicted existed were discovered.
Mendeleev left blank spaces in his periodic table to account for elements that had not yet been discovered. He predicted the properties of these missing elements based on the patterns he observed in the table. This empty spaces allowed for the periodic table to be a predictive tool for the discovery of new elements.
No, Mendeleev grouped the elements by atomic mass and chemical properties to create the periodic table. While there may be some correlation between element density and position on the periodic table, density was not the primary factor Mendeleev used for organization.

he arranged his Periodic Table by each elements Atomic Mass
Yes, Dmitry Mendeleev is credited with creating the periodic table in 1869. He arranged the elements based on their properties and predicted the existence of some elements that were discovered later. His work laid the foundation for the modern periodic table.
