Did You Know?

1

It’s a tribute! Curium gets its name from the legendary scientists Marie and Pierre Curie, the rockstars of radioactivity research.

2

Don't go digging for it! Curium is a synthetic element, meaning scientists create it in labs – it doesn't just hang out naturally in Earth's crust.

3

Making it is a cosmic billiard game! Scientists craft Curium by smashing plutonium atoms with alpha particles – talk about atomic alchemy!

4

Radioactive Powerhouse! Curium is incredibly radioactive, mostly blasting out powerful alpha particles which are heavy-duty atomic projectiles.
