A) \[Z=80,\,\,A=207\]
B) \[Z=82,\,\,A=208\]
C) \[Z=92,\,\,A=209\]
D) \[Z=90,\,\,A=207\]
Correct Answer: B
Solution :
Decrease in mass number due to \[6\alpha =6\times 4=24\] Decrease in change number due to \[6\alpha =6\times 2=12\] Increase in change number due to four \[\beta =4\] \[\therefore \] Net mass number \[=232-24=208\] Net atomic number \[=90-12+4=82\]You need to login to perform this action.
