Re: What does Uranium look like? What are its colors? Does it shine?

Uranium is a silvery-white metal. Metal surfaces in air will oxidize to a 
dark gray.  Compounds with oxygen, fluorine, nitrogen, etc. yield many 
different colors.  For example, U3O8 is yellow, UO2 is brown, UF4 is 
green.  Other compounds yield red, orange, black, white, and pale blue.  
Uranium metal that is finely divided (powdered) is pyrophoric (will 
spontaneously combust), especially in moist air.  Some compounds are more 
pyrophoric than the metal.  Sorry, I don't have a picture, but any 
textbook of minerals and metals should have a picture.
