Mass Spectrometry
In this video Paul Andersen explains how a spectrometer was used to identify the presence of isotopes. This modified Dalton's original atomic theory because atoms of the same element had different masses. The functional parts of a mass...

TED-Ed: The genius of Mendeleev's periodic table - Lou Serico
The elements had been listed and carefully arranged before Dmitri Mendeleev. They had even been organized by similar properties before. So why is Mendeelev's periodic table the one that has endured? Lou Serico explains via Ekaaluminium,...

Will the Periodic Table Ever Be Complete?
Recently, humanity filled the periodic table up to atomic number 118, which nicely rounds out that row. But are we done yet? Have we discovered all of the different elements? And what is an "island of stability?"
