Uranium Facts for Kids

Uranium is a chemical element (a metal) on the periodic table.It has an atomic number of 92, which means that a uranium atom has 92 protons in its center, which is called a nucleus.Uranium that is dug out of the ground will be made from three different isotopes: three different types of uranium with different numbers of neutrons in their nuclei.Most of it is Uranium-238; uranium-235 is less ...

Fission | Student Energy

Uranium is the most widely used fuel for nuclear fission. Uranium is a nonrenewable energy source but it is a common metal found as an ore worldwide. Nuclear power plants use uranium, enriched in the isotope U-235 for fuel because, unlike the more common U-238, it can fission.

Thorium - Academic Kids

Thorium as a nuclear fuel. Thorium, as well as uranium, can be used as fuel in a nuclear reactor.Although not fissile itself, thorium-232 (Th-232) will absorb slow neutrons to produce uranium-233 (U-233), which is fissile. Hence, like uranium-238 (U-238), it is fertile. In one significant respect U-233 is better than uranium-235 and plutonium-239, because of its higher neutron yield per ...

uranium - Students | Britannica Kids | Homework Help

Uranium is a silvery metal that is very dense—more than 19 times denser than water. One of the most distinctive properties of uranium is its radioactivity, which was discovered by the French physicist Antoine-Henri Becquerel in 1896. Radioactive isotopes of uranium decay to other elements or isotopes at well-defined rates called half-lives.

Uranium-238 - Academic Kids

Uranium-238 is the most common isotope of uranium found. When hit by a neutron, it becomes uranium-239, an unstable element which decays into neptunium-239, which then itself decays, with a half-life of 2.355 days, into plutonium-239.. Around 99.284% of naturally occurring uranium is uranium-238, which has a half-life of 1.41 × 10 17 seconds (4.46 × 10 9 years).

Applications. Uranium metal is very dense and heavy. Depleted uranium (almost pure 238 U with less than 0.2% 235 U) is used by some militaries as shielding to protect tanks, and also in parts of bullets and missiles, as it is extremely dense.The military also uses enriched uranium (more than natural levels of 235 U) to power nuclear propelled navy ships and submarines, and in nuclear weapons.

What is Uranium? How Does it Work - World Nuclear Association

Natural uranium as found in the Earth's crust is a mixture largely of two isotopes: uranium-238 (U-238), accounting for 99.3% and uranium-235 (U-235) about 0.7%. The isotope U-235 is important because under certain conditions it can readily be split, yielding a lot of energy.
