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 … Meer weergeven 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. It is malleable Meer weergeven Origin Along with all elements having atomic weights higher than that of iron, uranium is only naturally formed by the r-process (rapid … Meer weergeven Uranium, like all elements with an atomic number greater than 82, has no stable isotopes.

What is the diameter of a uranium atom? – MassInitiative
WebSo U is uranium. The atomic number of uranium is 92. The mass number for this isotope is 235. So how many protons, electrons, and neutrons in this atom of uranium? So once again for protons, we look at the atomic number, that's 92. So there must be 92 protons. In a neutral atom, the number of electrons is equal to the number of protons. WebWith his colleagues at the University of California at Berkeley, Glenn Seaborg discovered the element plutonium in late 1940. He went on to identify several more of the radioactive “transuranium” elements—so … barcelona best kebab
