U-238 has 92 electrons.
In the Periodic Table it is found at the bottom of the table, in the Actinides Period.
Atomic No. 92 is U (Uranium)
This number tells us that there are 92 protons and 92 electrons in an atom of uranium .
The Atmoic Mass is 238 . This is made up of the total number of protons and neutrons in the nucleus of U .
Hence the number of neutrons is 238 - 92 = 146.
Uranium exhibits several isotopes.
U-235 ; 92 protons , 92 electrons & 143 neutrons
U-236 ; 92 protons, 92 electrons & 144 neutrons
U-238 ; 92 protons, 92 electrons & 146 neutrons.
Notice for all the isotopes of 'U' the number of protons and electrons remains the same at '92' each. It is the different number of neutrons that make for different isotopes.
The name 'Uranium' comes from the planet 'Uranus' , which it turn comes from Classical Greek God, 'Uranus', the God of the sky.
U
Isotope U-238 has 92 electrons. This number corresponds to the atomic number of uranium, which is 92.
A neutral atom of (^{238}_{92}\text{U}) would have 92 electrons, as the atomic number (92) is equal to the number of protons (positively charged particles) and electrons (negatively charged particles) in a neutral atom.
Uranium has two valence electrons; possible valences are 6, 5, 4, 3, 2, 1.
U from uranium235U and 238U (recommended); also possible U-235 and U-238 or uranium-235 and uranium-238.
Si-28: 14 protons and electrons, 14 neutronsNi-60: 28 protons and electrons, 32 neutronsRb-85: 37 protons and electrons, 48 neutronsXe-128: 54 protons and electrons, 74 neutronsPt-195: 78 protons and electrons, 117 neutronsU-238: 92 protons and electrons, 146 neutrons
Isotope U-238 has 92 electrons. This number corresponds to the atomic number of uranium, which is 92.
Uranium is a chemical metal element. There are 92 electrons in a single atom.
A neutral atom of (^{238}_{92}\text{U}) would have 92 electrons, as the atomic number (92) is equal to the number of protons (positively charged particles) and electrons (negatively charged particles) in a neutral atom.
Uranium 240 has 92 protons and electrons, but 148 neutrons because the atomic number is 92 and the atomic mass is 240.
Uranium has two valence electrons; possible valences are 6, 5, 4, 3, 2, 1.
