Assembling the Modern Periodic Table

The messy road to periodic chemistry - The road to our modern-day periodic table was winding, full of dead ends and wrong turns. It required numerous discoveries, scientists, and experiments, as well as numerous failures and triumphs. It was, essentially, typical of science. Although we like to think of science evolving through lone geniuses like Mendeleev vaulting us toward progress, the reality of science is that it’s messy, requires extensive collaboration, builds on the work of others, and revises hypotheses when new information comes to light.
