Can You Actually Destroy an Atom? | NuclearVerse Ep 10

Can you destroy an atom? NuclearVerse Ep 10 finds out. The atoms in your hand are older than the Earth. They've survived fire, oceans and exploding stars. So can anything actually destroy one? In this NuclearVerse episode we test the idea that atoms are indestructible. We go from Democritus's "uncuttable" atomos and Dalton's 1808 atomic theory, to why burning a log never destroys a single atom, to Thomson's electron, the first crack in the atom. Then we find out why the nucleus is about 600,000 times tougher than its electron shell, how uranium breaks itself apart (Becquerel, 1896), how Rutherford changed nitrogen into oxygen in 1919, and why splitting one uranium nucleus releases about 50 million times more energy than burning one carbon atom. Finally: has anyone ever seen a proton die? Super-Kamiokande has been watching for decades. ⚛️ A new NuclearVerse episode every day.
