238 minus 92 is 146. Simple math.
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.
U-238 (Uranium-238) has 92 Electrons
Uranium 240 has 92 protons and electrons, but 148 neutrons because the atomic number is 92 and the atomic mass is 240.
Uranium 238 has 92 protons and 146 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.
The answer is Uranium 92 (238.0289)
92
180 - 92 = 88
92 - 26 = 66
The most common isotope of uranium is uranium-238. The atomic number of uranium is 92, which means it contains 92 protons. To calculate the number of neutrons, subtract the number of protons from the mass number 238. No. of neutrons in 238U = 238 - 92 = 146
-88
