Uranium

Some uranium mines in Argentina: Cachocira and Engenlio; in the past Don Otto.

About 64 kilograms- but only about 600 milligrams was converted to energy. See the link below for a good article on Little Boy.

Morocco is not now mentioned as a country with uranium reserves; but phosphates ores contain exploitable uranium (approx. 200 mg/kg).

Kazakhstan is the country that produces the most uranium, but large areas of uranium deposits include the area of Central Asia, Southwestern Australia, and the area around the Great Lakes.

Natural uranium, a heavy metal, is not explosive. It is, however, quite reactive chemically. As a fine powder, if it is was thrown into the air, it would spontaneously begin burning as it is pyphoric. (As an aside, it's a very toxic heavy metal.) No amount of uranium will just "blow up" like the detonation of a brick of plastique (plastic explosive). But there is a bit more to know.

If uranium is enriched to increase its U-235 concentration, it can be come explosive if critical mass is reached and "maintained" for a very short duration via explosives. This is the basis for the operation of a nuclear weapon. Note, however, that under normal circumstances, any assemblage of uranium to critical mass (for that concentration of isotopes and the physical conditions) will cause fission to begin. The fission will release enough energy to immediately force the critical mass apart and stop the reaction, though the "mess" resulting will be highly radioactive one. These so-called criticality accidents have occurred from time to time, and they are uniformly tragic (and almost always fatal).

Uranium has more that one valiance state. In one form it is quite soluble, in another not so soluble. That is why as oxygen became more plentiful and uranium a higher oxidation level it became soluble and dissolved in African rivers. It precipitated when the river met the ocean. There it created an atomic pile.

Uranium is a metal. You probably want the oxide or some other compound. Look up the solubility product constant for Uranium oxide. That will give you the exact figure for whatever valence and compound you want.

They don't.

Carbon-14 has a short half-life and is normally only used by archaeologists or anyone working on sediments less than 50,000 years old. It becomes much less accurate after 40,000 years.

Scientists used many different isotopes for dating rocks in Radiometric Dating, uranium/lead, potassium/argon and others are used. The half-life in some of these isotopes is measured in millions or billions of years.

The uranium ticker symbol is UX. The chemical symbol is U.

The electron dot diagram for uranium (U) will have 7 dots around the chemical symbol. Uranium has 7 valence electrons, so you would represent them as dots around the symbol "U" in no particular arrangement.

Uranium itself is a heavy, metallic element that is solid at room temperature. It does not have any physical sensations or emotions as it is an inanimate object. However, it is important to handle uranium with care due to its radioactive properties.

It is technically possible to mix gold with uranium, but it is not a common practice due to the contrasting properties and purposes of the two metals. Gold is typically valued for its appearance and malleability, while uranium is used primarily for its radioactive properties in nuclear applications. Mixing the two metals would likely not serve a practical purpose.

Yes, uranium is used in atomic bombs as a key component for fission reactions. Both uranium-235 and uranium-238 isotopes can be used in the production of nuclear weapons, with uranium-235 being the preferred isotope due to its higher reactivity.

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

Uranium can be harnessed through mining it from the earth's crust, mainly through open-pit or underground mining operations. It is typically found in concentrations in rocks and minerals, which are then processed to extract the uranium for various uses such as nuclear power generation.

It may sound silly, but neutrons are all pretty much alike. And they're very close in size to a proton. If you're looking for some numbers, try these: Radius: 1.1 x 10-15 m Mass: 1.6749×10-27 kg Note that there is variability in the mass. And yes, we already said they were all alike. Thing is, when neutrons are in a nucleus, they have to drop a bit of mass to make a contribution to what is called binding energy or nuclear glue. A neutron has a bit less mass in a nucleus than a free neutron. But a free neutron is unstable and has a half life of a bit less than 15 minutes. Fair trade? Note that you could "touch up" numbers a bit, but we're talking about something so small that the quantification you have before you will work for just anything in the undergraduate course list.

1. For the non-irradiated uranium the effect is unnoticed.

2. If you think to nuclear fission of uranium, this is another question.

Examples:
Oxides: uranium dioxide, uranium trioxide, uranium octaoxide
Salts: ammonium diuranate, uranyl nitrate, uranyl acetate, uranium hehxafluoride, uranium chloride
and many others because uranium is a reactive metal.

All the isotopes of uranium (in neutral state) have 92 electrons.

Uranium is primarily found in the Earth's crust, with most deposits located in countries such as Australia, Kazakhstan, Canada, and Russia. It is often extracted from ores like pitchblende and uraninite, and can also be found in small quantities in soil, rocks, and water.

Uranium is a naturally occurring heavy metal element found in the Earth's crust. It is not classified as a stone, but rather as a metal. Uranium is primarily known for its radioactive properties and uses in nuclear power generation and weaponry.

Yes, uranium is not typically used in medicines. In some cases, it may be used as a source of radiation for certain medical treatments, such as radiation therapy for cancer. However, its use is very limited due to its potential toxicity.

Disadvantages of uranium: is radioactive and toxic.

Uranium, Neptunium and Plutonium follow each other - elements 92,93,94. They are named after the outer planets though Pluto is no longer classed as a planet. U was chosen as there was no conflict with other elements names beginning with U.

It is impossible to know exactly this value; probably approx. 5.109 tons. But only a very small part of this quantity is economically to extract today.

9.6 grams of uranium (1 mole U/238.0 grams)(6.022 X 10^23/1 mole U)

= 2.4 X 10^22 atoms of uranium
