Then it is made into an oxide for storage and later use. What exactly is uranium? Uranium is a naturally occurring chemical element. It is the heaviest naturally occurring element known on Earth. It has 92 protons and was formed in supernovae explosions. Where is uranium found? Uranium is...
Uranium is a chemical element; it has symbol U and atomic number 92. It is a silvery-grey metal in the actinide series of the periodic table. A uranium atom has 92 protons and 92 electrons, of which 6 are valence electrons. Uranium radioactively decays by emitting an alpha particle. The...
It occurs as a naturally radioactive silvery-white metal and is one of the more common chemical elements in the Earth’s crust. Denoted by the symbol U, it has atomic number 92 in the periodic table of elements, meaning its nucleus contains 92 positively charged proto...
Uranium (pronounced /jʊˈreɪniəm/ yoo-RAY-nee-əm) is a silvery-white metallic chemical element in the actinide series of the periodic table with atomic number 92. It is assigned the chemical symbol U. A uranium atom has 92 protons and 92 electrons. 6 of the latter are val...
meaning that they have the same number of electrons and protons. The uranium that is mined from the earth is called natural uranium. Natural uranium contains 0.7%235U, with the balance being238U. Some nuclear reactors were designed to operate with fuel made of natural uranium, whereas other re...
Uranium is a chemical element with the symbol U and atomic number 92. Uranium-238 is the most common isotope which means it has the same chemical properties and atomic number but differs in mass. Isotopes have the same number of protons and electrons, but a different number of neutrons. Ura...
carbon-14 (six protons + eight neutrons), which is rare and unstable (or radioactive) As we see with carbon, most atomic nuclei are stable, but a few aren't stable at all. These nuclei spontaneously emit particles that scientists refer to as radiation. A nucleus that emits radiation is,...

known as actinides. actinides are dense because their nuclei contain large numbers of neutrons and protons. but it's the strange behavior of those nuclei that has long made actinides the stuff of wonder. at intervals that can vary from every millisecond to every hundred thousand years, ...
At some point thestabilityof the orbital electrons in the ordinary sense must be destroyed as more protons are added to the nucleus. There is, therefore, a criticalatomic number, or range of atomic numbers, which represents the end of the periodic table. This end, it should be noted, is ...
