These couple of questions have fustrated me very much.... I do not know the answer and was hoping someone does.... Thanks!
1. As bismuth 210 emits electrons, the mass of the daughter nuclei formed
a. increases
b. decreases
c. remains the same
d. none of the above
2. When uranium 238 changes into plutonium in an atomic reactor, the number of neutrons in atomic nuclei
a. increases
b. decreases
c. remains the same
d. none of the above
Thank you so much if you are able to help!!!

in alpha decay the daughter nuclei will have 2 protons and 2 nutrons always. the mass of the bisthmus will decrease. 1-remains the same
Since the atomic number is changing the nuclei is changing. it increases the number to that of plutonium. 2-a

Emission of e = beta emission, where one neutron becomes a proton, so the mass of the nucleus REMAINS THE SAME.
Really sorry. That's all i remember...
Hope this helps.
And hope this helps ALSO.
