What is the second rarest element?
It is extremely radioactive; its most stable isotope, francium-223 (originally called actinium K after the natural decay chain it appears in), has a half-life of only 22 minutes. It is the second-most electropositive element, behind only caesium, and is the second rarest naturally occurring element (after astatine).
What is the coolest element?
Plutonium. Pretty much all of the radioactive elements are cool. Plutonium is particularly awesome because it truly does glow in the dark. Plutonium’s glow isn’t due to its radioactivity, though.
