Final answer:

In the early 1800s, elements were classified by atomic masses, and Mendeleev introduced gaps for undiscovered elements, predicting their properties.


Explanation:

In the early 1800s, elements were classified primarily based on atomic masses, where elements with similar properties were arranged together.

Mendeleev made two significant changes to the early periodic tables: he arranged elements based on atomic masses but left gaps for undiscovered elements, and he predicted properties of these missing elements that matched those of later-discovered elements, solidifying the acceptance of his periodic table.
