The Incredible Discovery of the LEAST Reactive Elements (The Noble Gases)

The noble gases were hiding in plain sight! Learn how these “lazy” elements were discovered, from the completely unique discovery of argon to finding the 'sun-element' - helium. Following this were the rapid-fire discoveries of krypton, neon and xenon, and finally, the deadly discovery of radon. Watch to find out how their unique properties transformed our understanding of the periodic table and chemical reactivity! 👨‍🔬 Interested in bonus content?
