ChemistryInteger+4Question 37 of 60

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?
$^{63}_{29}\mathrm{Cu}+{}^1_1\mathrm H\to6\,{}^1_0\mathrm n+\alpha+2\,{}^1_1\mathrm H+\mathbf X$

Your answer

Answer and worked solution

Official answer: 8

Balance the nuclear equation.

Mass: $63+1=6(1)+4+2(1)+A$ , so $A=52$ .
Charge: $29+1=0+2+2(1)+Z$ , so $Z=26$ .

X is $^{52}_{26}$ Fe. Iron is in group 8.
