Did You Know?
Discovered by the incredible Marie Curie and Pierre Curie in 1898! Marie, a Polish-French scientist, named it after her home country, Poland – talk about patriotism!
Polonium is one of the rarest elements on Earth, occurring naturally in tiny, *tiny* amounts as a product of uranium decay. You won't just stumble upon it!
This element is *super* radioactive, emitting alpha particles like a tiny, nuclear cannon. Just a gram of Polonium-210 can generate enough heat to glow red-hot!
Speaking of heat, Polonium-210 is so incredibly energetic that it can self-heat significantly. This property was once explored for spacecraft power sources!
