A nuclear transformation is denoted by X...

A nuclear transformation is denoted by `X(n,alpha) rarr. _(3)^(7)Li`. Which of the following is the nucleus of element `X`

A

`""_(5)^(9)B`

B

`""_(4)^(11)Be`

C

`""_(6)^(12)C`

D

`""_(5)^(10)B`

Text Solution

Verified by Experts

The correct Answer is:
D
The nuclear transformation is given by
`""_(Z)^(A)X+""_(0)^(1)n rarr""_(2)^(4)He+""_(3)^(7)Li`
According to conservation of mass number
`Z+0=2+3 or Z=5`
So, the nucleus of the element be `""_(5)^(10)B`.
