See the lists below for the exact concentrations in the Earth crust and for minerals.
no. uranium and thorium occur in nature
Francium exists in uranium and thorium ores.
Actinium is found in uranium and thorium ores.
Uranium and thorium are in the actinoids family.
Actinium exist in minute traces in uranium and thorium ores.
Thorium is abundant than uranium in nature. It can be used to generate power.
Thorium: 90 protons Uranium: 92 protons
Uranium and thorium minerals contain radon.
Uranium 238 is transformed in thorium 234 by alpha decay.
Yes, we can get more electricity from thorium, if you are asking about the supply. When 232Th is used in a nuclear reactor, it is bred to become 233U. This isotope of uranium has about as much energy available as 235U, so the amount of energy per fission event is about the same for thorium as it is for uranium. Aside from that, however, there are important differences. Thorium does not need to be enriched, so all of it can be used. The amount of thorium we have is a multiple of the amount of uranium. The combination means that, where we only have a few decades supply of uranium, we have enough thorium to last thousands of years.
When uranium radiates alpha particles, it transforms into thorium. Thorium is a radioactive element that is produced as a result of the decay of uranium through alpha emission.
