The nuclide `""_(99)^(247)Es` can be obtained by bombarding `""_(92)^(239)U` in a reaction that emits 5 neutrons . The bombarding particle is

A

`""_(2)^(4)He`

B

`""_(1)^(3)H`

C

`""_(7)^(13)N`

D

`""_(-1)^(0)e`

Text Solution

Verified by Experts

The correct Answer is:
C
`""_(94)^(239)U + ""_(m)^(n)X rarr ""_(99)^(247)Es + 5""_(0)^(1)n`
`239 + n = 247 + 5 xx 1 implies n=13`
`92 + m = 99 implies m=7`
`therefore ""_(m)^(n)X =""_(7)^(13)N`
