According to the research, the correct option is Mendeleev predicted elements that would later be discovered.
<h3>What is the periodic table of Mendeleev?</h3>
This is the first version of the periodic table and was made up of a column with 63 elements, grouped according to their common properties, and several blank spaces.
Specifically, the Russian chemist Dmitri Mendeleev assumed that some elements that had not been discovered were missing, those corresponding to atomic masses that were not yet known and that allowed the table to have an absolute numerical regularity.
Therefore, we can conclude that according to the research, the correct option is Mendeleev predicted elements that would later be discovered.
