Who first discovered thorium? – Sage-Answer
WebIt was discovered in 1938 that neutron bombardment could cause uranium to split, or fission, and release a large amount of energy. With the subsequent determination that the uranium-235 ( 235 U) isotope not only fissioned but also emitted additional neutrons, the prospect emerged of a sustained chain reaction and production of usable energy. WebThorium Ore is an ore which generates naturally upon world creation in the Cavern layer, becoming increasingly common further down in the world.
