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?

$_{29}^{63}Cu+_{1}^{1}H-6_{0}^{1}n+_{2}^{4}\alpha+2_{1}^{1}H+X$

Answer:

Option C

Explanation:

Balancing the given nuclear reaction in terms of atomic number (charge) and mass number gives

$_{29}Cu^{63}+_{1}H^{1}\rightarrow6_{0}n^{1}+_{2}He^{4}(a)+2_{1}H^{1}+_{2}He^{4}+_{26}X^{52}$

The atomic number 26 correspond to transition metal "Fe" which belongs to 8^th group of modern Periodic Table
