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 ​ α + 2 1 1 ​ H + X

29 63 ​ Cu + 1 1 ​ H → 6 0 1 ​ n + 2 4 ​ He + 2 1 1 ​ H + Z A ​ X Balancing the atomic mass and atomic number 63 + 1 = ( 6 × 1 ) + 4 + 2 + A ⇒ A = 52 29 + 1 = ( 6 × 0 ) + 2 + 2 + Z ⇒ Z = 26 Thus Z A ​ X = 26 52 ​ X or 26 52 ​ Fe Hence, X belongs to group 8 in the periodic table.
