    This document contains questions about John Dalton's and Dmitri Mendeleev's development of the periodic table, including how they organized the elements, why it is called the periodic table, and how the order changed with the discovery of electrons, protons and neutrons. It also asks how Mendeleev overcame problems with early periodic tables being incomplete and some elements being placed in inappropriate groups.
