That picture is NOT Uranium:
Uranium is a chemical element; it has symbol U and atomic number 92. It is a silvery-grey metal in the actinide series of the periodic table.

That picture is uranium though? In the picture it has yellow oxides forming on the outside.
In the same way that if someone posted a picture of a rusty piece of iron, we’d still say it was iron, even though iron is a silvery-grey metal, but in the picture, it would be reddish/brown.
