WebBut helium doesn't naturally bond to anything. You have to really, REALLY try to get any sort of bond with helium at all under anything resembling normal Earth conditions, and even then the resulting compounds are wildly unstable (much too unstable to exist naturally). So all helium on Earth exists as just regular old free gaseous helium. Web8 nov. 2024 · On Earth, helium is generated deep underground through the natural radioactive decay of elements such as uranium and thorium. "It takes many, many … WebAlthough a further bill was passed in 2013 to extend the reserve’s operation, and with countries like Qatar and Russia investing in helium production, Ballentine explains that supplies of the gas are still thin on the ground. ‘Nobody’s ever really looked for helium before,’ he says. small boat hoist
