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
`_(29)^(63)Cu+_(1)^(1)H rarr 6_(0)^(1)n+_(2)^(4)alpha+2_(1)^(1)H+X rArr 64=6+4+2+A rArr A=52`
`29+1=30=0+2+2+z rArr z=26 rArr `Element `X` should be ion in group `8`.
