The number gives number of nucleons in a nucleus. Ask your question. What is a sample Christmas party welcome address? Properties of atomic nuclei (atomic mass, nuclear cross-sections) are determined by the number of protons and number of neutrons (neutron number). Isotopes of an element have the same number of protons but different number of neutrons since their mass numbers are different. Uranium-235 is an isotope of Uranium-238, all this means is that Uranium-235 has the same number of … d. the total number of protons and neutrons in an atom of an element. Determine the number of protons and the number of neutrons in uranium-235 and write its symbol in the form AZX. Nuclides that have the same neutron number but a different proton number are called isotones. number of 92, the number of neutrons is 143. New questions in Chemistry. 92 electrons. Uranium 235 has. For example, the neutron number of uranium-238 is 238-92=146. Uranium-235 is used in nuclear fission. U-235 therefore contains 235 - 92 = 143 neutrons.
