How The Periodic Table Was Created

Listen to my podcast here: https://pods.to/rationalthinker Join my Patreon: patreon.com/RationalThinker In 1875, French chemist Paul-Émile Lecoq de Boisbaudran discovered the element 'Gallium' after isolating it from a zinc blende ore. However, shortly after his publication, he received word from a Russian chemist with the name of "Mendeleeff" that claimed he had predicted such an element to exist 6 years earlier. This is the story of how that Russian chemist - and a fellow German chemist - turned rival - uncovered the periodic law of the elements and formulated them all into one cohesive unit, transforming chemistry forever.
