a. `._(25)Mn^(56)` b. `._(24)Cr^(56)` c. `._(24)Mn^(56)` d. `._(24)Cr^(56)`

A

`""_(25)^(55)Mn`

B

`""_(24)^(55)Cr`

C

`""_(25)^(55)Mn`

D

`""_(24)^(56)Cr`

Text Solution

Verified by Experts

The correct Answer is:
A

The reaction is an example fo neutron `-gamma` -particle emission
`""_(25)Mn^(55)+ ""_(0)n^(1) rarr ""_(25)Mn^(56) + gamma`-radiations
