Uranium-238 Number of Protons and Neutrons
The three nuclides U-233 U-235 and U-238 are isotopes because they have a different numbers of neutronsThus option C is correct. The isotopes of Uranium thus have the. Radioactivite Radioactive Series Radioactive Physics Classroom Nuclear Physics The uranium nucleus binds between 141 and 146 neutrons establishing six isotopes U-233 through U-238 the most common of which are uranium-238 146 neutrons and uranium-235 143 neutrons. . A neutral atom of uranium U has 146 neutrons and a mass number of 238. Of protons Z 92. Helium has 2 protons 2 neutrons and 2 electrons. The total mass of an element is the sum of its protons and neutrons. Mass no is integer value Mass no. Therefore number of neutrons is the atomic mass minus the atomic number. Uranium-238 U238 has three more neutrons than uranium-235 U235. Answer 1 of 2. 12 What does thorium-234 alpha decay into. Number of neutrons typical isotop...
