A) A and C are isobars
B) A and C are isotopes
C) A and B are isotopes
D) A and B are isobars
Correct Answer: B
Solution :
\[_{Z}{{A}^{A}}{{\xrightarrow{{}}}_{Z-2}}{{B}^{A-4}}{{+}_{2}}H{{e}^{4}}\] \[_{Z-2}{{A}^{A-4}}{{\xrightarrow{{}}}_{Z}}{{B}^{A-4}}+2\,e_{-1}^{0}\] A and C have the same atomic number but different mass numbers, therefore A and C are isotopes.You need to login to perform this action.
