Phase diagram of the Actinides. Credit James L. Smith, LANL. Taken from the English Wikipedia and converted from gif.

Original Caption: "Connected binary-phase diagram (temperature vs. composition) of the actinides. Such diagrams demonstrate the transition from typical metallic behavior at thorium to the enormous complexity at plutonium and back to typical metallic behavior past americium. With little provocation plutonium will change its density by as much as 25 percent. It can be as brittle as glass or as malleable as aluminum; it expands when it solidifies. Its unusual behaviour is just one of the challenges of understanding plutonium." This is a work of the Los Alamos National Laboratory and as such is in the public domain.
