Uranium
Uranium is a heavy element with the atomic number 92 and the symbol U. In 1789 it was discovered in the mineral pitchblende by Martin Heinrich Klaproth , who named it after the planet Uranus

Uranium can appear shiny when freshly cut or polished, but over time it may tarnish and dull. The level of shine can vary depending on the specific form and condition of the uranium sample.
How much is one kilogram of Uranium?
The cost of uranium varies wildly depending on who is selling it, and who is buying it. If you are looking for black market prices, they will obviously be high. But if you are looking for the low-radioactive uranium in uranyl compounds for pottery, the costs can be very low.
Trans-uranium elements are synthetic elements with atomic numbers greater than uranium (92). These elements are produced in laboratories through nuclear reactions and are typically radioactive with short half-lives. Many trans-uranium elements are involved in research and nuclear applications.
Yes. That is an ionized uranium atom. It is very similar to U-235, which is used in nuclear reactors.
Yes, it is used but the rest of the above answer is entirely wrong.
U-238 is not ionized! It is just the isotope that makes up 99.274% of natural uranium and typically 99.7% or more of depleted uranium. It will not support a fission chain reaction but can be made to fission by very high energy neutrons such as those produced in hydrogen fusion.
Both U-235 and U-238 are present in any reactor or uranium fueled bomb. Typical reactor fuel is 3% U-235 and 97% U-238, while oralloy (the usual uranium bomb fuel) is 93.5% U-235 and 6.5% U-238.
Both uranium and plutonium fueled fission bombs use a uranium tamper around their core. This is either depleted (≥99.7% U-238) or natural (99.274% U-238) uranium.
Fusion bombs use a fission bomb primary stage to trigger fusion in their fusion secondary stage.
Fusion bombs often use a uranium tamper around the fusion stage(s). This is either depleted (≥99.7% U-238) or natural (99.274% U-238) uranium. In some designs the fission of this U-238 can provide as much as 90% of the total yield of the bomb (and a corresponding amount of its fallout).
So U-238 is present in some amount in every nuclear reactor and every kind of nuclear weapon.
Applications of uranium:
- nuclear fuel for nuclear power reactors
- explosive for nuclear weapons
- material for armors and projectiles
- catalyst
- additive for glasses and ceramics (to obtain beautiful green colors)
- toner in photography
- mordant for textiles
- shielding material (depleted uranium)
- ballast
- and other minor applications
Is uranium a form of chemical energy?
No, since uranium in a radioactive element, it stores Nuclear energy.
Actually metallic uranium stores lots of chemical energy and can burn violently. Finely divided metallic uranium is even pyrophoric (it will ignite on exposure to air).
How do you dispose of depleted uranium?
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 colors)
- toner in photography
- mordant for textiles
- shielding material (depleted uranium)
- ballast
- and other minor applications
Does the government use uranium?
Yes, the government uses uranium.
Uranium is mined, refined and then enriched to provide nuclear fuel for nuclear reactors. Depleted uranium, the uranium "left over" from enrichment, is used in munitions to defeat armor, and in some types of armor. On a related note, enriched uranium is in demand by some sovern states and religeous/political factions to make nuclear weapons, though the "modern" nuclear powers use plutonium as the fissionable element in their nuclear devices. The plutonium is made by "soaking" uranium in the neutron flux of an operating nuclear reactor for a time. This changes (transmutes) some of the uranium to plutonium, which is then recovered and processed.
Uranium belongs to the actinide family of elements in the periodic table.
Uranium is volatile or non volatile?
Uranium is considered non-volatile in its natural state. However, when it is processed and enriched for use in nuclear reactors or weapons, it can become volatile and pose a significant hazard if not handled properly.
What is the electronegativity of Uranium?
The electronegativity of Uranium is around 1.38 based on the Pauling scale. Uranium is a metal with relatively low electronegativity compared to nonmetals like oxygen and fluorine.
What is the availability of uranium?
Uranium is not so plentiful; one day the reserves will be exhausted.
Applications of uranium:
- nuclear fuel for nuclear power reactors
- explosive for nuclear weapons
- material for armors and projectiles
- catalyst
- additive for glasses and ceramics (to obtain beautiful green colors)
- toner in photography
- mordant for textiles
- shielding material (depleted uranium)
- ballast
- and other minor applications
Is uranium a conductor or insulator?
The electrical resistivity of uranium is 28.10-8 ohm.meter; uranium is not an electrical insulator.
What is gaseous diffusion in uranium enrichment?
One of several methods of enriching uranium (increasing the percentage of uranium-235 in the product).
Gaseous diffusion uses porous nickel metal membranes as diffusion barriers. Pumps increase the pressure of the uranium hexafluoride gas on one side of the barriers causing the gas to diffuse through. The lighter uranium-235 atoms moving slightly faster than the uranium-238 atoms, becoming a bit more concentrated on the far side.
The enriched product on the far side is then sent on to the next stage in the cascade while the depleted product on the near side is sent back to the preceding stage. Then after thousands of these stages, each providing a tiny amount of enrichment, the final product having the desired enrichment is produced (as well as large quantities of depleted waste product).
How many atoms of uranium are present in 1 nanogram of uranium?
1 nanogram of natural uranium = 2,53.1012 atoms
What is the pronunciation rebus of uranium?
Rebus = Re as in religion, bus an in school bus
Manganese = manga as in the Japanese files, nese as in Chinese
What is the ionic charge of uranium?
AS a metal the charge is zero, in a compound it depends on the compound, it has more than one oxidation state.
What is the most dangerous use of uranium?
For making energy in nuclear reactors. Highly enriched uranium could also be used in war fare as well.
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 colors)
- toner in photography
- mordant for textiles

What are the benefits of uranium?
1. Uranium is important for nuclear reactors, for the production of clean energy (no contribution to global warming and air pollution). 2. Uranium is important for nuclear weapons. 3. Uranium has many other minor applications in chemical industry, ceramics, glass industry, electronics, photography, for armors, etc.
most metals in their natural state are not green of flourescent. uranium in it's natural state is silver grey, but some forms can be made to look green under a blacklight or other curcumstances.
What is uranium's impact on Georgia?
