Scientists suggest Mendeleev left gaps in the Periodic Table because Mendeleev knew the elements existed; however, was unable to prove it.
Mendeleev left gaps in his periodic table because the properties of known elements predicted other, as-yet-undiscovered, elements in these locations. As Mendeleev organized his periodic table, he recognized that these gaps would be filled as future scientists identified new elements.
So scientists in the future could find undiscovered elements
he knew that because of the new elements that were formed and he figured that the atoms would pop back and forth and leave gaps in between them.
he predicted that there were elements not yet discovered so yeah.
Gaps
DiscoVery of new elements
he knew that later on the gaps would eventually get filled up
Mendeleev left some gaps in his table for the elements which were not discovered at that time.Those elements were later found as silicon,gallium,germanium which were then filled in the gaps
Because those elements were not discovered at the time Mendeleev proposed the periodic table.
he knew that because of the new elements that were formed and he figured that the atoms would pop back and forth and leave gaps in between them.
he predicted that there were elements not yet discovered so yeah.
Atomic numbers.

Gaps
DiscoVery of new elements

Mendeleev left those gaps for the elements which were not discovered at that time. He named those elements like eka-aluminium,eka -silicon etc.
it helped in the discovery of new elements
