What daughter isotopes are produced when a neutron combines with a nucleus of 235/92 U? Assume that three neutrons are also produced in the reaction.
A. 140/56 Ba, 95/36 Kr
B. 142/56 Ba, 93/36 Kr
C. 140/56 Ba, 93/36 Kr
D. 141/56 Ba, 94/36 Kr
Please help. Thanks.
With 3 neutrons produced, the sum of the atomic weights of the daughter product nuclei must be 235 + 1 - 3 = 233
The atomic number (proton) sum for the daughter nuclei must be 92
Only one of the four choices satisfines these criteria.
Now you know how to make the choice.
Thank you for your help!
