Women in Chemistry: Heroes of the Periodic Table

To honor women’s history month in the international year of the periodic table, today we wanted to share the story of two of chemistry’s most brilliant and bold women and their paths of elemental discovery -- because what they brought to the table changed the world as we know it. 

Note: There is a voice over error. The voice over states that by 1879 Marie Curie had concluded that Uranium and Thorium were the only known radioactive elements. This date should actually be 1897. Apologies for this error.
