A neutron causes the element 88X232 to change according to the reaction 0n1 + 88

Question

A neutron causes the element 88X232 to change according to the reaction 0n1 + 88X232 ---->ZYA + . Identify the (a) atomic number and (b) atomic mass number of the daughter nucleus. (c) This product subsequently undergoes - decay, and its daughter does too. Identify the atomic number of the final nucleus. (d) Give the atomic mass number of this final nucleus.

Explanation / Answer

(a) atomic number = z = 0+88 = 88 (b) atomi mass number = A = 1+232 = 233 (c) the element is radium 0n1 + 88Ra233 ---->88Ra234 and Ra 224 under goes alpha decay to 88Ra234 -> 2He4 + 86Rn220 atomic number of final nucleys is 86 (d) atomic mass numer of final nucleus is 220
