Uranium (92U) is a naturally occurring radioactive element that has no stable isotope. It has two primordial isotopes, uranium-238 and uranium-235, that have long half-lives and are found in appreciable quantity in the Earth's crust. The decay product uranium-234 is also found. Other isotopes such as uranium-233 have been produced in breeder reactors. In addition to isotopes found in nature or nuclear reactors, many isotopes with far shorter half-lives have been produce… Web8 mei 2014 · Physicists have created one of the heaviest elements yet, an atom with 117 protons in its nucleus.

Uranium is a chemical element with 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 half-life of this decay varies between 159,200 and 4.5 billion years for different isotopes, making them useful for dati… Web7 apr. 2024 · The mass of uranium- 238 is 238 mass units.

Web29 mei 2024 · So that means Uranium is going to lose two protons and 2 neutrons. U-238 has 92 protons and (238-92 = 146 neutrons). If it loses 2 protons and 2 neutrons, it will then have 90 protons and 144 neutrons. The element with 90 protons is Thorium, Th, and it will have a mass number of 144+90 = 234. WebAs all uranium nuclei have 92 protons, the nucleus of a uranium-235 atom will also have 143 neutrons to give it a total atomic mass number of 235.
