YouTube description:

How did early scientists know to leave gaps for undiscovered elements on the periodic table? Astrophysicist Neil deGrasse Tyson tells the story of how Dmitri Mendeleev used a subatomic particle to organize the elements. Also, find out how helium got its name - and who uses more of the voice-changing element than Macy’s. Finally, Neil tells comic co-host Chuck Nice what happened when his personal radiation detector went off in a hospital.
