Because the Atomic Mass of this isotope is approx. 235 atomic units of mass.
92 electrons - the number of electrons is the same in all the isotopes of uranium. Number of electrons = Number of protons = Atomic number
Uranium has 92 electrons and protons.Uranium-234 has 142 neutrons, uranium-235 has 143 neutrons and uranium-238 has 146 neutrons.
All the isotopes of uranium contains 92 protons and electrons but a different number of neutrons.
When uranium-235 is added to natural uranium, it increases the overall percentage of uranium-235 in the mixture. This can make the uranium more suitable for use in nuclear reactors or weapons, as uranium-235 is more fissile (more easily split by neutrons) than uranium-238.
Uranium-235 and uranium-238 are natural, radioactive isotopes of uranium; they have 92 protons and electrons but the number of neutrons is different: - for 235U: 143 - for 238U: 146
Uranium 235 (and also all the isotopes of uranium) has 92 electrons.
Uranium 235 has several isotopes but, 235 would contain 235 electrons in one atom.
92 electrons - the number of electrons is the same in all the isotopes of uranium. Number of electrons = Number of protons = Atomic number
Valences of uranium: 3,4,5,6 and possible 2 (in UO).
Uranium-235 has 92 protons and 92 electrons. This is because the number of protons in an atom is equal to its atomic number, which is 92 for uranium. The number of electrons is also equal to the number of protons in a neutral atom.
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.
Uranium has 92 electrons and protons.Uranium-234 has 142 neutrons, uranium-235 has 143 neutrons and uranium-238 has 146 neutrons.
For example the isotope uranium-235 contain 92 protons and electrons, 143 neutrons.
The atomic number of uranium is 92. The number of neutrons of the isotope uranium-235 is 143.
All the isotopes of uranium contains 92 protons and electrons but a different number of neutrons.
A stable isotope of uranium-235 contains 143 neutrons.
Uranium-235 is an isotope of uranium making up about 0.72% of natural uranium.
