""(92)U^(235) nucleus absorbs a neutron ...

`""_(92)U^(235)` nucleus absorbs a neutron and disintegrates into `""_(54)Xe^(139) .""_(38)Sr^(94)` and X. What will be the product X ?

3 neutrons

2 neutrons

`alpha`-particles

`beta`-particles.

Text Solution

Verified by Experts

The correct Answer is:

`""_(92)U^(235)+""_(0)n^(1) to ""_(54)Xe^(139)+ ""_(38)Sr^(94) + ""_(Z)X^(M)`
`235 +1 =139 + 94 + M " or " M=3`
92+0=54 + 38 + Z or Z =0
Hence X=3 neutrons.
