238 minus 92 is 146. Simple math.
Isotope U-238 has 92 electrons. This number corresponds to the atomic number of uranium, which is 92.
238 - 145 = 93
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.
In a uranium-238 atom, the number in the isotope name stands for the total number of protons and neutrons in the nucleus. So in this case, uranium-238 has 92 protons (atomic number) and 146 neutrons (238 - 92).
Uranium 240 has 92 protons and electrons, but 148 neutrons because the atomic number is 92 and the atomic mass is 240.
The answer is Uranium 92 (238.0289)
92
180 - 92 = 88
92 - 26 = 66
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.
all isotopes of uranium have 92 protons, that is what makes them uranium.
