Uranium
Pitchblende is uranium ore, so any nuclear weapon which used uranium in some form or other (tamper, core, used with plutonium, secondary casing) would need uranium, which is initially obtained from the mining and refining of pitchblende, for example, Little Boy.
0.242 t of oxygen; but the value is only an approximate because the pitchblende is not only pure UO2.
Uraninite, AKA pitchblende, is an ore of uranium.
