Coefficient of Thermal Expansion of Protactinium (Pa) & Facts, Color, Uses ...

Size of things changes depending on the coefficient of thermal expansion. It's even the case for Protactinium. Ok, so what is the coefficient of thermal expansion for an atom of Pa?

Note: Learn more about the coefficient of thermal expansion here.

In the case of Protactinium this thermal coefficient is 9.7 10^-6 K^-1. By the way, did you know there are cool facts about Protactinium that most don't know? Check this...
