Solved: The two most common isotopes of uranium are 235U
Chapter , Problem 110IE(choose chapter or problem)
The two most common isotopes of uranium are \({ }^{235} \mathrm{U} \mathrm{and}^{238} \mathrm{U}\)
(a) Compare the number of protons, the number of electrons, and the number of neutrons in atoms of these two isotopes.
(b) Using the periodic table in the front-inside cover, write the electron configuration for a U atom.
(c) Compare your answer to part (b) to the electron configuration given in Figure 6.30. How can you explain any differences between these two electron configurations?
(d) \({ }^{238} \mathrm{U}\) undergoes radioactive decay to \({ }^{234} \mathrm{Th}\). How many protons, electrons, and neutrons are gained or lost by the \({ }^{238} \mathrm{U}\) atom during this process?
(e) Examine the electron configuration for Th in Figure 6.31. Are you surprised by what you find? Explain.
