from the splitting of uranium atoms
Existing element is product of nuclear fusion, heavy element exist from over fusion and thus create high atomic mass substance. To answer what is the element that is form last in nuclear fusion in star is the same as asking what is the heaviest element occur or found in nature. Base on what is in periodic table. The heaviest element found naturally is around Uranium - Plutonium thus it could be considered the last product known in nuclear fusion in star. There are heavier element than Uranium and Plutonium but those are synthesize element. Nuclear fusion might go to element heavier than what is known in our periodic table but those substance may be unstable and decay over time until none of those exist.
Nuclear fusion on earth has not been achieved in any way that could produce power, but experiments continue.
yes
Nuclear fission may do, though with fast breeder reactors we could make use of the large amount of Uranium 238 which is not useful at present, as we only use the U235 in the present type of reactors. In the long term (probably 100 years or so) nuclear fusion may be usable, and this really would extend nuclear power for thousands of years.
Uranium itself does not blast or explode on its own. It can undergo a process called nuclear fission in a controlled environment such as a nuclear reactor, leading to a highly energetic chain reaction. Uncontrolled fission could result in a nuclear explosion.
I could answer is the question was more specific.
Its really hard to say, the only nuclear bomb that might contain that much uranium (probably as depleted uranium) would be a hydrogen fusion bomb with a uranium tamper.Depending on many design features, it would probably weigh a bit under 2 tons and have a yield somewhere between 2 megatons and 20 megatons, most of that produced by fission of the uranium tamper.NO nuclear bomb could ever contain that much weapons grade uranium, as it would be so far beyond critical that it would simply melt in the factory as it was being assembled and kill anyone nearby with neutron and gamma radiation.
It cold be considered renewable as in some nuclear fission reactors; called breeder reactors; more fuel could be produced than what is consumed and on the other hand uranium is one of the most abundant minerals on earth crust and water. On the other hand, fusion nuclear energy is based on unlimited resources of deuterium and tritium.
The most likely nuclear fusion reaction to be successful in power production is between deuterium and tritium, which are both isotopes of hydrogen. The element formed in this fusion reaction is helium. So the only two elements involved are hydrogen and helium.
The costs of nuclear fusion energy are currently high due to the complexity and advanced technology required for fusion reactions. Research and development costs are significant, as well as costs associated with building and maintaining fusion reactors. However, advancements in technology and increased investment in fusion energy could help lower costs in the future.
Without uranium, nuclear power plants would not be able to produce energy the way they do now. This could lead to increased reliance on other forms of energy, such as fossil fuels, which could contribute to environmental issues like pollution and climate change. Additionally, nuclear weapons production would be impacted since uranium is a key component in their creation.
