1) a)Calculate BE/A for 235U, the rarer of the two most common uranium isotopes. Enter your answer using 4 significant figures.
b) Calculate BE/A for 238U. (Most of uranium is 238U.) Note that 238U has even numbers of both protons and neutrons. (Is the BE/A of 238U significantly different from that of 235U?) Enter your answer using 4 significant figures.

Uranium has 3 naturally occurring isotopes; 238U, 235U, and 234U. Roughly 99.2745% of uranium is U-238 and 0.7200% is U-235. What is the average mass of an U atom? You may assume that the mass of each isotope is equal to its mass number. Report your answer to 6 sig figs. How many protons, neutrons, and electrons does 235U have?

The two isotopes of uranium, 235U (atomic mass 235.04 amu) and 238U (atomic mass 238.05 amu), can be separated by a gas-diffusion process by combining them with fluorine to make the gaseous compound UF6 (atomic mass of fluorine is 18.998 amu). Part A Calculate the ratio of the rms speeds of these molecules for the two isotopes, at constant T. Express your answer using five significant figures.

Enter your answer in the provided box. The 235U isotope (atomic mass = 235.00) undergoes fission when bombarded with neutrons. However, its natural abundance is only 0.72 percent. To separate it from the more abundant 238U isotope (atomic mass = 238.00), uranium is first converted to UF, which is easily vaporized above room temperature. The mixture of 23SUF, and 238UF gases is then subjected to many stages of effusion. Calculate how much more quickly 235UF, effuses than 238UF. Give the...

A Review Constants 1 Periodic Table Subm Previous Answers Correct When identifying isotopes of an atom, we look for atoms that have the same number of protons but different masses. This means that each isotope has a different number of neutrons. In an atomic symbol of an isotope, the upper left number represents the mass number (which consists of the sum of protons and neutrons in the nucleus of the atom) and the lower left number is...
