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 rarr 6 ._(0)^(1)n + alpha + 2 ._(1)^(1)H + X

Answer»


SOLUTION :`._(29)^(63)Cu + ._(1)^(1)H rarr 6 ._(0)^(1)N + ._(2)^(1) alpha + 2 ._(1)^(1) H + X`
`64 = 6 + 4 + 2 + A rArr A = 52`
`29 + 1 = 30 = 0 + 2 + 2 + z rArr z = 26`
element X should be iron in GROUP 8
