✓ Answer: A Pitchblende
The elements such as neptunium and plutonium were found in Pitchblende. Pitchblende is a radioactive mineral and the primary ore of uranium. Elements like neptunium and plutonium are not naturally abundant but are formed as by-products in nuclear reactors or during the decay of uranium found in pitchblende. Plutonium-239 is produced by neutron capture in uranium-238, which is abundant in pitchblende.
