What's Inside an Atom's Nucleus? | NuclearVerse Ep 11

What is inside the nucleus of an atom? NuclearVerse Ep 11 takes you inside. A sugar cube made only of atomic nuclei would weigh about 230 million tons. That's roughly 40 Great Pyramids you could hold between two fingers. So what is this tiny, impossibly dense thing at the heart of every atom? In this episode we find out how small a nucleus really is (femtometers!), how Robert Hofstadter measured its fuzzy edge by firing electrons at it, why every nucleus has the same density like drops of water, why radium-224 is shaped like a pear, and why lithium-11 is as big as lead. ⚛️ A new NuclearVerse episode every day.
