What was the chemical element uranium named after what planet?
It was the other way round. Uranium was named after a planet. That planet was Uranus.

Benefits of uranium mining in Saskatchewan?
Applications of uranium:
- nuclear fuel for nuclear power reactors
- explosive for nuclear weapons
- material for armors and projectiles
- catalyst
- additive for glass and ceramics (to obtain beautiful green or yellow colors)
- toner in photography
- mordant for textiles
- shielding material (depleted uranium)
- ballast
- and other minor applications
Also a mine or plant need workers and the unemployement will be lower.

How many Electrons in uranium 235?
Because the atomic mass of this isotope is approx. 235 atomic units of mass.
Is solar energy contained in uranium?
No, solar energy is derived from the sun's radiation, while uranium is a radioactive element used in nuclear power plants to generate electricity through a process called nuclear fission. Solar energy and uranium are distinct sources of energy with different origins and methods of generation.
What are the masses of uranium and in uranium oxide?
The percentage of uranium in uranium dioxide is 88,149.
How is uranium 235 different from uranium 231?
Uranium-235 is a natural isotope with 143 neutrons.
Uranium-231 is an artificial isotope with 139 neutrons.
Where can fossil fuels be used?
Fossil fuels are used in thermal power stations for production of electricity. They are used as automobile fuels i.e petroleum. They are used in factories and industries as power source like in Iron or Steel industries.
How did the Holocaust gets its name?
The Holocaust refers to the murder of about 6 million Jews by the Nazis in World War 2. Sometimes other victims of Nazi mass killings are also included, in which case the total number of victims is much higher than 6 million.
The term The Holocaust in this specific sense has been in widespread use since the late 1970s. Before that it was referred to as the Final Solution [of the Jewish Question]. This was not a very satisfactory term as it was a translation of the Nazis' own term for the genocide.
The word holocaust (with a small h and without The) means: 1. great destruction, especially by fire; 2. whole burnt offering.Because of the religious connotations of the word, some people prefer to use the word Shoah (Hebrew for great calamity, disaster).
In addition to the Jews, the Nazi killed many other groups. Some people include these other groups, some don't.
The modern, specific sense of Holocaust was popularized by Elie Wiesel from the late 1950s onwards.

There are thought to be about 5 million tons of the grade of ore being mined now, typically 0.1 to 0.25 percent uranium oxide. So that represents 5000 to 12500 tons of uranium. This will keep the industry going for some years yet. Eventually lower grade ores will have to be mined which will be more expensive, but there is no reason to expect a shortage.
What size of nuclear bomb made with one ton of uranium?
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.
What is the correct order of nuclear decay mode for the changes from U-238 to U-234?
The correct order of nuclear decay mode for the changes from U-238 to U-234 is alpha decay followed by beta decay. In alpha decay, the nucleus emits an alpha particle, reducing its atomic number by 2 and mass number by 4, resulting in Th-234. This is followed by beta decay, where a neutron is converted into a proton, producing U-234.
What does the breakdown of uranium release?
When uranium undergoes radioactive decay, it releases alpha, beta, and gamma radiation. This breakdown process results in the transformation of uranium isotopes into different elements, known as its decay chain. This chain typically includes elements such as radium, radon, and lead, each with its own unique radioactive properties and emissions.
Where do you get the word uranium from?
The name of the chemical element uranium is derived from the name of the planet Uranus; and Uranus was a god in the Greek mythology.
What is the mass of 7.50 moles of uranium?
The mass of 7,5 mole of natural uranium is 238,02891 x 7,5 g.
What are reactor and uranium are used in the production of?
A nuclear reactor is a facility which produce electricity and heat from the fission of uranium or plutonium.
The energy released by fission of uranium-235 (or other isotopes) is immense compared to the energy content of fossil fuels.
The discovery of the element is credited to the German chemist Martin Heinrich Klaproth. While he was working in his experimental laboratory in Berlin in 1789.
He found an uranium oxide (which he had named after the planet Uranus which had recently been discovered) in pitchblende ores.
The pure element was isolated in 1841 by Eugene Melchior Peligot.
