What is true about uranium atoms? ›

A uranium atom has 92 protons and 92 electrons, of which 6 are valence electrons. Uranium has the highest atomic weight of all naturally occurring elements. Uranium occurs naturally in low concentrations in soil, rock and water, and is commercially extracted from uranium-bearing minerals such as uraninite.

Uranium is the fuel most widely used by nuclear plants for nuclear fission. Uranium is considered a nonrenewable energy source, even though it is a common metal found in rocks worldwide. Nuclear power plants use a certain kind of uranium, referred to as U-235, for fuel because its atoms are easily split apart.

Uranium is an actinide element, and has the highest atomic mass of any naturally occurring element. In its refined state, it is a heavy, silvery-white metal that is malleable, ductile, slightly paramagnetic, and very dense, second only to tungsten.

What is it used for? Uranium “enriched” into U-235 concentrations can be used as fuel for nuclear power plants and the nuclear reactors that run naval ships and submarines. It also can be used in nuclear weapons.

* Uranium can damage the kidneys, the liver, and the blood cells (anemia). * Repeated exposure can cause permanent scarring of the lungs (pneumoconiosis). * Uranium powder is FLAMMABLE and a FIRE HAZARD. * Uranium is a radioactive isotope and is regulated by the Nuclear Regulatory Commission (NRC).

With a half-life of 4 billion years, uranium is only very weakly radioactive. In fact, since uranium is a heavy metal, its chemical toxicity is actually more of a danger than its radioactivity. If you touch it directly with your hands, you should wash your hands afterwards. You should not eat it.

The arrangement of particles within uranium-235 is somewhat unstable and the nucleus can disintegrate if it is excited by an outside source. When a U-235 nucleus absorbs an extra neutron, it quickly breaks into two parts. This process is known as fission (see diagram below).

Nuclear power plants use a certain type of uranium—U-235—as fuel because its atoms are easily split apart. Although uranium is about 100 times more common than silver, U-235 is relatively rare at just over 0.7% of natural uranium.

Uranium is weakly radioactive and contributes to low levels of natural background radiation. The majority of background radiation occurs naturally and a small fraction comes from man-made elements. in the environment.

Uranium is a silvery white, weakly radioactive metal. It has a Mohs hardness of 6, sufficient to scratch glass and approximately equal to that of titanium, rhodium, manganese and niobium.

Is uranium high in energy? ›

Uranium is an abundant metal and is full of energy: One uranium fuel pellet creates as much energy as one ton of coal, 149 gallons of oil or 17,000 cubic feet of natural gas. It does not come out of the ground ready to go into a reactor, though. It is mined and processed to create nuclear fuel.

Nuclear is a zero-emission clean energy source. It generates power through fission, which is the process of splitting uranium atoms to produce energy. The heat released by fission is used to create steam that spins a turbine to generate electricity without the harmful byproducts emitted by fossil fuels.

Uranium is the most-used fuel by nuclear power plants for nuclear fission.

Uranium production & consumption worldwide

Uranium consumption is the highest in the United States, France, and China.

Uranium occurs naturally in the earth's crust. In the United States, it is found most abundantly in the western states [EPA 2006a, b, c; Lide 1994; USGS 2009b]. Enrichment of uranium for nuclear weapons began in the 1940s and for energy production in the 1950s.

A radioactive, silvery metal. Uranium is a very important element because it provides us with nuclear fuel used to generate electricity in nuclear power stations. It is also the major material from which other synthetic transuranium elements are made.

Uranium is the fuel most widely used to produce nuclear energy. That's because uranium atoms split apart relatively easily. Uranium is also a very common element, found in rocks all over the world. However, the specific type of uranium used to produce nuclear energy, called U-235, is rare.
