Definition of uranium in English:

uranium

noun jʊˈreɪnɪəmjʊˈreɪniəm

mass noun

The chemical element of atomic number 92, a dense grey radioactive metal used as a fuel in nuclear reactors.
（化学元素）铀（符号： U ）
Uranium is a chemically reactive metal belonging to the actinide series. Becquerel discovered radioactivity in uranium in 1896, and its capacity to undergo fission led to its use as a source of energy, though the fissile isotope, uranium-235, has to be separated from the more common uranium-238 before it can be used in nuclear weapons. The atom bomb exploded over Hiroshima in 1945 contained uranium-235
Example sentencesExamples
- This time it was uranium and iron ore which provided the much needed employment opportunities.
- To develop a comprehensive set of nuclear weapons, enriched plutonium and uranium are needed.
- He advises the villagers to drink a lot of milk because the calcium compounds with uranium.
- The heavy elements like gold or lead or uranium are very rare in the universe.
- The chemical toxicity of uranium is also well known, though somewhat less well understood.
- There are large unexploited nickel deposits, and uranium, vanadium, and gold.
- Workers there recently learned that they were exposed to both plutonium and uranium.
- Depleted uranium is derived from natural uranium mined from the earth's crust.
- All countries have uranium, uranium is a very common material around the world.
- Radioactive uranium oxide pellets were found in a controlled area of the plant.
- The Curies discovered radium, a radioactive substance, in uranium oxide ore.
- Depleted uranium is an extremely dense substance derived from enriched uranium.
- Enrichment is a process of purifying uranium for use as nuclear fuel or in weapons.
- A highly radioactive solution of water, plutonium and uranium is constantly leaking out.
- It is not certain if the effects are due to the chemical or the radioactive properties of uranium.
- Radon is produced when trace amounts of uranium and radium in the soil or rocks decay.
- However, uranium is a heavy metal and the safety limits are based on its toxicity as a metal.
- It is not possible, however, to construct weapons directly out of uranium or slightly enriched uranium.
- And extracting uranium and storing nuclear waste both produce carbon emissions.
- Enrichment can produce different grades of uranium that can be used for fuel or nuclear warheads.

Origin

Late 18th century: modern Latin, from Uranus: compare with tellurium.

A rare radioactive metal, uranium is found in the mineral pitchblende. The German chemist Martin Klaproth isolated the metal and called it uranium after the planet Uranus, which the astronomer Sir William Herschel had discovered less than a decade before, in 1781.

Rhymes

cranium, geranium, germanium, Herculaneum, titanium
