Uranium in ores is extracted chemically and converted into uranium dioxide or other chemical forms usable in industry.
It is malleable, ductile, slightly paramagnetic, strongly electropositive and a poor electrical conductor.
However, because of the tiny amounts found in nature, uranium needs to undergo enrichment so that enough uranium-235 is present.
Uranium-238 is fissionable by fast neutrons, and is fertile, meaning it can be transmuted to fissile plutonium-239 in a nuclear reactor.
Uranium has the highest atomic weight of the primordially occurring elements.
Its density is about 70% higher than that of lead, and slightly lower than that of gold or tungsten.
