- It is a fissile material: uses in nuclear reactors and nuclear bombs
- It is radioactive, emitting radiations and releasing heat: use as radio-isotopic heating units
- Being an alpha particle emitter is used in neutron sources as Pu-Be.
Uranium is now the most important nuclear fuel.
Under nuclear fission with thermal neutrons uranium release an enormous quantity of energy (202,5 MeV per one atom of 235U); the obtained heat is converted in electricity.
Applications of uranium:
- nuclear fuel for nuclear power reactors
1. Uranium is an alternative to fossil fuels, especially for countries without reserves of coal, petrol, methane.
2. Uranium don't contribute to global warming.
3. Uranium don't release carbon dioxide.
4. In the future uranium can be extracted from the sea water.
- 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
- additive for the preparation of biological samples for electron microscopy
- shielding material (depleted uranium)
- ballast (counter weights)
- and other minor applications
Uranium dating is useful for long periods of time - e.g. 109 years. For fossils is recommended the method with 12C.
Dna fibers
Francium occurs naturally, although extremely rare. It can and is made in labs. Although it is considered a naturally occurring element, there is only about one ounce of it in the Earth's crust at any one time. Scientists reproduce it in labs so they can study it, ect. So little is known about Francium now; if we didn't reproduce it in labs we would know next to nothing about it.
Uranium is found in many compounds, though not all these compounds are useful. Notably, however, a uranate is a particular oxide involving uranium in different oxidation states, and is often found in that state in other compounds, such as ammonium diuranate.
Zinc (Zn)
i think it is uranium
only me
Uranium is a natural chemical element, solid, radioactive, unstable, having a great density, also atomic weight, with moderated reactivity, toxic, useful etc.
Zirconium is a stable element with a high tolerance for heat, making it ideal (in a nuclear reactor) for encasing uranium fuel in cylindrical "fuel rods" with very minimal contortion, making sure the rod does not jam in the reactor, which may have... undesirable consequences
Uranium is more common and useful.
Uranium is a very useful material but uranium is also toxic an radioactive.
no. but uranium-239 is the most useful and it is very rare.
Uranium ore is a heterogeneous mixture
Uranium dating is very useful to evaluate the age of rocks and minerals.
- the nuclear energy from uranium is an alternative for fossil fuels- uranium doesn't release carbon dioxide- uranium hasn't a contribution to the warming of the climate- uranium has many applications- uranium is useful for nuclear weapons, armors and projectiles
- workers in uranium mines - workers in uranium plants (recovery of uranium from minerals and transformation in useful compounds) - workers in enrichment facilities - workers in nuclear fuel plants - workers in uranium research laboratories etc.
Uranium fission with thermal neutrons release an enormous quantity of energy; this heat is converted in electricity.
