Write equations for the following transformation:
(a) `._(7)^(17)N (n, p)` (b) `._(19)^(39)K(n, alpha)`

Text Solution

Verified by Experts

(a) `._(7)N^(14)(n,p)` indicates that `N^(14)` on bombardment with neutrons gives proton.
`:. " " ._(7)N^(14)+._(0)n^(1) rarr ._(z)X^(m)+._(1)p^(1)`
on eqating at. "no". And mass "no". "on" both sides, we get
`._(7)N^(14)+._(0)n^(1) rarr ._(6)C^(14)+ ._(1)p^(1)`
(b) `._(19)K^(39)(p,alpha)` indicates that `K^(39)` on bombarment with proton gives `alpha `-particle.
There, `._(19)K^(39)+._(1)H^(1) rarr ._(18)Ar^(36)+._(2)He^(4)`
(c) `._(11)Na^(22) rarr . _(10)Ne^(22)+ ._(+1)e^(0)(beta^(+)"or positron")`
