The fresh surface of pure plutonium is silvery.
The most straightforward way to make a pure sample of calcium is to electrolyze a molten calcium salt with an "inert" cathode such as platinum. Considerable care is required to prevent reaction of pure calcium with the ambient atmosphere.
compare the samples density with that of pure gold
No, plutonium occurs only in trace amounts in nature, and it's too reactive to occur as a pure metal.
