Uranium

Uranium is not magnetic in its natural state. However, certain isotopes of uranium can be paramagnetic under specific conditions.

In 1789 Martin Heinrich Klaproth discovered an uranium oxide. In 1841 Eugène-Melchior Péligot obtained the first pure uranium metal.

Uranium is primarily used in nuclear power plants to produce electricity. It is also used in some military applications, such as nuclear weapons. Additionally, uranium can be used in certain medical procedures and in some research applications.

Uranium is radioactive and toxic. The risk is dependent from the chemical form (oxyde, solution, metal, fluorides, etc.), physical form (metal, sintered oxyde, powders, aerosols, liquids), enrichment, irradiated or not; also importants are the radioactive descendents of uranium, especially the gas radon.

The end element of the uranium decay chain is a stable isotope of lead.

Uranium is radioactive, and contamination of water, air or the human system can be fatal or permanently mutate a person or living animal's body, therefore, it is advised not to use uranium and instead use some safer resource.

Uranium-238 is a naturally occurring radioactive isotope with a very long half-life. It is commonly used in nuclear reactors as fuel for generating electricity through nuclear fission. Despite being weakly radioactive, Uranium-238 does not pose a significant health risk unless ingested or inhaled in large quantities.

Uranium-235 decays primarily through alpha decay, where it emits an alpha particle (helium nucleus) and transforms into thorium-231.

The biggest uranium company in the world is Kazatomprom, a state-owned entity in Kazakhstan. It is responsible for producing a significant portion of the world's uranium supply. Other major uranium companies include Cameco Corporation and Paladin Energy.

Uranium is produced mainly by mining operations around the world. Extraction methods include open-pit mining, underground mining, and in-situ recovery techniques. The largest producers of uranium include countries like Kazakhstan, Canada, Australia, and Namibia.

According to the World Nuclear Association, as of 2009, the largest producer of uranium was Kazakhstan. See the link below for a complete list. Prior to 2009 it was Canada, which is now the second largest producer of Uranium.

Uranium reserves are in:

Kazakhstan, Australia, Canada, United States, Namibia, Gabon, Niger, Malawi, South Africa, Brazil, Argentina, France, Spain, Germany, Romania, Czech Republic, Ukraine, Uzbekistan, China, Russia, Iran, Greenland, Algeria, Bulgaria, Hungary, etc.

Uranium can be found in small quantities in some meteorites, especially those known as carbonaceous chondrites. These meteorites are valuable for studying the early solar system and can contain various radioactive elements, including uranium, which provides insights into the age and formation of the meteorite. Scientists use uranium isotopes in meteorites to date their formation and understand processes like nucleosynthesis in the early universe.

The atomic bomb works by a physical phenomenon known as Fission. In this case, particles, specifically nuclei, are split and great amounts of energy are released. This energy is expelled explosively and violently in the atomic bomb. The massive power behind the reaction in an atomic bomb arises from the forces that hold the atom together called the strong nuclear force. The element used in atomic bombs is Uranium-235. Uranium's atoms are unusually large, and henceforth, it is hard for them to hold together firmly. This makes Uranium-235 an exceptional candidate for nuclear fission. Uranium is a heavy metal and has many more neutrons than protons. This does not enhance their capacity to split, but it does have an important bearing on their capactiy to facilitate an explosion. When a U-235 atom splits, it gives off energy in the form of heat and Gamma radiation, which is the most powerful form of radioactivity and the most lethal. When this reaction occurs, the split atom will also give off two or three of its "spare" neutrons, which are not needed to make either of the parts after splitting. These spare neutrons fly out with sufficient force to split other atoms they come in contact with. In theory, it is necessary to split only one U-235 atom, and the neutrons from this will split other atoms, which will split more...so on and so forth. This progression does not take place arithmetically, but geometrically. All of this will happen within a millionth of a second. Uranium is not the only material used for making atomic bombs. Another material is the element Plutonium, in its isotope Pu-239. However, Plutonium will not start a fast chain reaction by itself. The material is not fissionable in and of itself, but may act as a catalyst to the greater reaction. The bomb basically works with a detonating head starting off the explosive chain reaction.

uranium is a radioactive substance which can cause mutations in cell while potassium is non-radioactive. in fact it is required in our body for transmission of nerve impulse and osmoregulation. ----------- Potassium-40 is also radioactive ! But uranium is also a toxic element and as a radioactive element is more dangerous that potassium (alpha particle emitter, gamma irradiation, radioactive descendents as radon).

The chemical symbol for Uranium is the letter "U".

Uranium is a dense, silvery-white metal that typically appears as a solid. It has a high atomic number and is slightly radioactive. In its natural state, uranium can be found in various mineral forms.

no, it serves no biological purpose in any multicellular organism. some primitive bacteria can use it in their metabolism to help convert their food to ATP though, but they can also use other chemicals similarly.

The price of uranium can vary widely depending on factors such as supply and demand, geopolitical events, and market speculation. In recent years, the price has been relatively low due to oversupply and decreased demand for nuclear energy.

Chemical properties: All of its isotopes are radioactive. It has a wide range of oxidation states. It is flammable and pyrophoric when finely divided.

Physical properties: It is silvery black in color. It is the only element having naturally occurring isotopes than can support a nuclear fission chain reaction.

Yes, uranium is still used today primarily as a fuel for nuclear power plants to generate electricity. It is also used in some medical treatments, as well as in certain military applications like in nuclear weapons.

it is exactly 238.02891 u ± 0.00003 u

or in other words you can write it as 395,256.10-24 grams

Electrons in uranium are arranged in energy levels and orbitals around the nucleus. Uranium has 92 electrons, with each electron occupying a specific orbital based on the Aufbau principle. The outermost electrons are involved in bonding and chemical reactions, determining the element's properties.

Uranium is a dense, silvery-white metal that is weakly radioactive. In its natural state, it has a metallic luster and can also appear as a black oxide when exposed to air. It is primarily used in nuclear reactors and weapons.
