Uranium

Uranium does not have a distinct odor. It usually appears as a silvery-white metal in its natural form and can have different colors when it forms compounds. For example, uranium oxide compounds can range in color from yellow to green to black.

Uranium has 92 electrons and protons.
Uranium-234 has 142 neutrons, uranium-235 has 143 neutrons and uranium-238 has 146 neutrons.

Uranium-237 will undergo beta minus decay to neptunium-237 according to the following equation: 92U237 => 93Np237 + e- + 0.519 MeV At the risk of being a bore, a neutron in U237 undergoes a weak interaction-mediated change into a proton and an electron. The electron will be ejected from the nucleus immediately. Along with the electron, which leaves with a lot of kinetic energy, we'll see an antineutrino and the decay energy (0.519 MeV).

No, carbon is not malleable. Pick a form, hit with a hammer, and it won't "flatten out" like, say, gold. Carbon in the form of graphite or diamond won't do well when struck.

Uranium is a radioactive element. It is in the f block. We use it for make energy.

Yes, uranium is oxidized in air even at room temperature (surface oxidation) but at high temperature the oxidation is total; the formed oxide is U3O8.

Uranium does not have a group it belongs to, but it is in period 7.

Uranium is a solid at normal temperatures, melting at 1132° C and vaporizing above 3818° C.

The lead atom is way heavier than the helium atom. We know this by referring to the Periodic Table of Elements. The atomic mass of lead (Pb) is 207, while that of helium (He) is 4. Therefore, we can estimate that an atom of lead is about 50 times heavier than an atom of helium.

Uranium is a natural chemical element, solid, metal.
Uranium is largely used as nuclear fuel in nuclear reactors to deliver energy (electricity or heat).

The price for the oxide U3O8 is cca. 0,08 USD/g.

One thing that can happen when a neutron interacts with a uranium atom is called scattering. The neutron "bounces off" the uranium. Aside from scattering, a neutron has a possibility of being absorbed by the uranium nucleus, and this can cause several different reactions, depending on which isotope of uranium is involved in the reaction. It is neutron absorption that is the mechanism utilized in the chain reactions in nuclear weapons and in nuclear reactors. Nuclear fuel, which is often uranium-235, fissions by absorbing a neutron. In the case of uranium-238, we make plutonium by getting that isotope to absorb a neutron. There is a lot more to learn, and you'll find related links below to get you going.

Uranium hexafluoride is made from uranium dioxide or uranium tetrafluoride by adding fluorine gas. The process involves reacting uranium compound with an excess of fluorine gas under controlled conditions to produce uranium hexafluoride.

No, Uranium has far more electrons.

In a neutral atom number of electrons=number of protons=atomic number.

Hydrogen has 1 electron. Uranium has 92.

A nuclear reactor is a plant which deliver electricity and (or) heat.
The function principle is the release of energy from nuclear fission of fissile materials as the isotope uranium-235.

The following is typical, but there are a number of variations, mostly minor:

Uranium is first found by exploration. It is then mined. The ore is milled to produce small pieces, which are then chemically leached to produce an uranate called yellocake. The yellowcake is reacted to produce uranium hexafluoride , which is then run through centrifuges to separate a heavier fraction from a lighter fraction. The lighter fraction is the enriched material used for power plants, the heavier is referred to as depleted. The enriched uranium is chemically converted to another oxide, uranium dioxide, and this is converted into the form of fuel used in plants, commonly by pressing and sintering. The fuel is encased in cladding of special steels or zircaloy, and then is ready to be put into the reactor.

There is a link to a more detailed answer below.

Uranium 235 is a natural isotope of uranium (the concentration is approx. 0,7 %); uranium 235 is separated from the other uranium isotopes by different methods (centrifugation, gaseous diffusion;also on small scale by laser, mass spectrometric, ion exchange, etc.).

The electron configuration of uranium is: [Rn]5f36d17s2.

I suppose that the real price of enriched uranium is partially secret and also depends on the contract and the signing data. Also is a link between price and politics !

The most important is the enrichment percent in 235U: 3 % or 93 % ? And the quality: nuclear grade, weapons grade, standards for analysis (extremely expensive), etc.

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.

An atom has neutrons, protons, electrons. A chemical element has isotopes. With some exceptions isotopes has no name, but a number, equal to atomic mass.
