This document discusses the contributions of several important figures in the development of the periodic table, including Berzelius, Dalton, Meyer, Mendeleev, and Seaborg. It asks questions about each of their key discoveries and how they helped establish the modern periodic table. These include Berzelius' atomic theory, Dalton's atomic theory, Meyer's periodic table publication, Mendeleev's periodic table and predictive successes, and Seaborg's addition of lanthanides and actinides below the main body of elements.

periodic table were made by Seaborg
when he adds lanthanides and actinides
below the periodic table.
Why do you think lanthanides and actinides were
