U-235 has 92 electrons and 92 protons.
It has 235-92 neutrons, i.e., 143
Uranium 235 has: 92 protons, 92 electrons and 143 neutrons.
All the isotopes of uranium has 92 protons.
Uranium has 92 protons and 92 electrons as its atomic number is 92. In U-235, there are 143 neutrons (235 - 92 = 143)
Uranium has 92 protons, and an uncharged atom will have 92 electrons. The number of neutrons is 235-92 = 143 neutrons.
143 neutrons
235Np has 142 neutrons and 93 protons.
uranium 235 proton
235 (mass number) - 92 (number of protons) = 143 (number of neutrons)
Protons = 92 Electrons = 92 Neutrons = 146 The number of electrons and protons in a neutral atom are each equal to the atomic number of the element (92). The number of neutrons equals the atomic weight minus the number of protons (238 - 92 = 146).Uranium has 92 protons, 92 electrons, and usually 147 neutrons, though another isotope has 143 neutrons.
Protons = 92 Electrons = 92 Neutrons = 146 The number of electrons and protons in a neutral atom are each equal to the atomic number of the element (92). The number of neutrons equals the atomic weight minus the number of protons (238 - 92 = 146).
The atomic number of uranium is 92. The number of neutrons of the isotope uranium-235 is 143.
Uranium 235 is 0.7 percent of natural uranium and is fissile
For the natural isotopes of uranium: Uranium 238 has: 92 protons, 92 electrons and 146 neutrons. Uranium 235 has: 92 protons, 92 electrons and 143 neutrons. Uranium 234 has: 92 protons, 92 electrons and 142 neutrons.
92 electrons - the number of electrons is the same in all the isotopes of uranium. Number of electrons = Number of protons = Atomic number
All the isotopes of uranium contains 92 protons and electrons but a different number of neutrons.
Uranium 235 (and also all the isotopes of uranium) has 92 electrons.
Because the atomic mass of this isotope is approx. 235 atomic units of mass.
92 protons 92 electrons, 125 to 150 neutrons depending on the isotope (natural or artificial). For the natural isotopes of uranium: Uranium 238 has: 92 protons, 92 electrons and 146 neutrons. Uranium 235 has: 92 protons, 92 electrons and 143 neutrons. Uranium 234 has: 92 protons, 92 electrons and 142 neutrons.
For example the isotope uranium-235 contain 92 protons and electrons, 143 neutrons.
Uranium 235 has several isotopes but, 235 would contain 235 electrons in one atom.
Uranium 235 has 92 protons and 92 electrons. To find the number of neutrons, follow this equation: Mass # - Atomic # = # of neutrons. Since the mass number of uranium 235 is 235 and has an atomic number of 92, the number of neutrons is 143.
235 (mass number) - 92 (number of protons) = 143 (number of neutrons)
An isotope means an atom with the same amount of electrons and protons, but with different amount of neutrons.Relative weight of a neutron is 1, a proton is 1, and an electron is very small. So weight of an atom is approx. mneutrons + m protons.So, an uranium-235, as U is the 92th atom in periodic table, contains 92 protons, 92 electrons to be chargeless, and 143 (=235-92) neutrons.An uranium-238, from the definition of isotope, contains 92 protons, 92 electrons, and 146 (=238-92) neutrons.The difference is the 3 neutrons.
Uranium-238 (atom number 92) has 92 protons and the neutral atom has 92 electrons. This is also true for the other isotopes of uranium, eg. U-235.
