Nuclear Chemistry Ques 8
8. The radioactive isotope ${ }_{27}^{60} \mathrm{Co}$ which is used in the treatment of cancer can be made by ( $n, p$ ) reaction. For this reaction the target nucleus is
[2004]
(a) ${ }_{28}^{59} \mathrm{Ni}$
(b) ${ }_{27}^{59} \mathrm{Co}$
(c) ${ }_{28}^{60} \mathrm{Ni}$
(d) ${ }_{27}^{60} \mathrm{Co}$
Show Answer
Answer:
Correct Answer: 8.(c)
Solution: (c) $[X]+\frac{1}{0} n \rightarrow{ }_{27}^{60} \mathrm{Co}+{ }_1^1 \mathrm{H}$
Balancing the mass and atomic numbers on both sides ${ } _ {28}^{60} X+{ } _ 0^1 n \rightarrow{ } _ {27}^{60} \mathrm{Co}+{ } _ 1^1 \mathrm{H}$
Thus $X$ should be ${ }_{28}^{60} \mathrm{Ni}$
