Uranium-235 is an isotope of Uranium-238, all this means is that Uranium-235 has the same number of protons and electrons as Uranium-238, but a different number of neutrons. It has 92 protons and 92 electrons. Because uranium is radioactive, it is constantly emitting particles and changing into other elements. Naturally occurring uranium consists of 99% uranium-238 and 1% uranium-235. Name: Radium: Symbol: Ra: Atomic Number: 88: Atomic Mass: 226.0 atomic mass units Number of Protons: 88: Number of Neutrons: 138: Number of Electrons: 88: Melting Point The chain reaction is carefully controlled using neutron-absorbing materials. Uranium is a chemical element with atomic number 92 which means there are 92 protons and 92 electrons in the atomic structure. It has 7 energy levels with 92 electrons, six of which are valence electrons. 8 years ago. The element Radon (Rn) has an atomic number of 86; bracketed, Rn indicates uranium having an atomic core of 86 electrons. Uranium has a common oxidation state of +6 and it also has +3, +4 and +5 numbers. UO 2 and UCl 4 has +4, UO 3 and UF 6 has +6. Uranium has an atomic number of 92 which means there are 92 protons and 92 electrons in the atomic structure. Uranium fuel used in nuclear reactors is enriched with uranium-235. 0 1. The atom consist of a small but massive nucleus surrounded by a cloud of rapidly moving electrons . The most common isotope is uranium-238, and all uranium isotopes are weakly radioactive because they do emit alpha radiation.It's density is much higher than lead but slightly lower than gold or tungsten, as 6 of the electrons are valence electrons. Uranium is a chemical element with the symbol U and atomic number 92. The Bohr model predicted that the square of number of electrons (Z 2) in any atom is proportional to the frequency of radiation emitted by it. It is a silvery-white metal in the actinide series of the periodic table. give the symbol and number of electrons in a neutral atom of 1.uranium 2.boron 3.antimony 4.chlorine 5.iodine 6.xenon Give the symbol and number of neutrons in one atom of 7.barium 8.carbon 9.fluorine 10. europium 11. hydrogen 12magnesium 13. mercury To find the number of neutrons, follow this equation: Mass # - Atomic # = # of neutrons. Uranium is a chemical element with symbol U and atomic number 92. Uranium is a radioactive element denoted by the chemical symbol U. Uranium is a chemical element with the atomic symbol U and atomic number of 92. As 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. U-238 has 146 neutrons in the nucleus, but the number of neutrons can vary from 141 to 146. yeah, look on the periodic table. Caroline Miller. A uranium atom has 92 protons and 92 electrons, of which 6 are valence electrons. Uranium 235 has 92 protons and 92 electrons. It is a silvery-white metal in the actinide family of elements. Energy levels depicting the valence electrons are shown as 5f3 6d1 7s2. Lv 7. Uranium is a chemical element with atomic number 92. The chemical symbol for Uranium is U . 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 is weakly radioactive because all isotopes of uranium are unstable; the half-lives of its naturally occurring isotopes range between 159,200 years and 4.5 billion years.
