`._(92)U^(238)` absorbs a neutron. The product emits an electron. This product further emits an electron. The result is

Text Solution

Verified by Experts

The successive processess may be expressed as
.`_(92)U^(238) overset (._(0)n^(1)) rarr. _(92)U^(239) overset (beta (electron)) rarr. _(93)Np^(239)`
overset(beta(electron)) rarr ._(94)Pu^(239)`
Thus, the resulting plutonium has atomic number 94 and mass number `239` and is expressed as `._(94)Pu^(239)`.
