Write the nuclear reactions for the following radioactive decay:
(a) `._(92)U^(238)` undergoes `alpha-` decay.
(b) `._(91)Pa^(234)` undergoes `Beta-` decay.
(c) `._(11)Na^(22)` undergoes `Beta^(+)` decay.

Text Solution

Verified by Experts

(a) `._(92)U^(238) rarr ._(90)Th^(234) + ._(2)^(4)He`
(b) `._(91)Pa^(234) rarr ._(92)U^(234) + ._(-1)^(0)e`
(c) `._(11)Na^(22) rarr ._(10)Ne^(22) + ._(+1)^(0)e`
