Nuclear Chemistry - Result Question 20
20. The periodic table consists of 18 groups. An isotope of copper, on bombardment with protons, undergoes a nuclear reaction yielding element $X$ as shown below. To which group, element $X$ belongs in the periodic table?
(2012)
$ { } _{29}^{63} Cu+{ } _1^{1} H \longrightarrow 6{ } _0^{1} n+{ } _2^{4} \alpha+2{ } _1^{1} H+X $
Show Answer
Answer:
Correct Answer: 20. (8)
Solution:
- Balancing the given nuclear reaction in terms of atomic number (charge) and mass number:
$ { } _{29} Cu^{63}+{ } _1 H^{1} \longrightarrow 6{ } _0 n^{1}+{ } _2 He^{4}(\alpha)+2{ } _1 H^{1}+{ } _{26} X^{52} $
The atomic number 26 corresponds to transition metal $Fe$ which belongs to 8th group of modern periodic table.
