Question

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?___
${}_{29}^{63}Cu{+}_1^{1}H\to 6_0^{1}n{+}_2^4\alpha +2_1^{1}H+X$

Answer 1

Balancing the given nuclear reaction in terms of atomic number (charge) and mass number:
${}_{29}C{u}^{63}{+}_1{H}^1\to 6_0{n}^1{+}_{2}H{e}^4\left(\alpha \right)+2_1{H}^1{+}_{26}{X}^{52}$
The atomic number 26 corresponds to transition metal Fe which belongs to 8th group of modern periodic table.
