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)Cu^(63)+._(1)H^(1)rarr6._(0)n^(1)+._(2)He^(4)(alpha)+2._(1)H^(1)+._(Z)X^(A)`

Answer 1

Correct Answer - 8
The given nuclear reaction is:
`._(29)^(63)Cu + ._(1)^(1)H to 6_(0)^(1) n + ._(2)^(4)He + 2_(1)^(1) H + ._(26)^(52)Fe`
The element `._(26)^(52)Fe` belongs to 8th group of periodic talbe.
