A necear transformation is denoted by `X (n,a) _(3)^(7)Li` Which of the following is the neclues of electron X?

A

`_(5)^(10) Be`

B

`^(12)C_(6)`

C

`_(4)^(11)Be`

D

`_(5)^(9)B`

Text Solution

Verified by Experts

The correct Answer is:
A
`_(z)X^(A) + _(0)n^(1) rarr _(3)Li^(7) + _(2)He^(4)`
On comparison,
`A = 7 + 4 - 1 = 10 , z = 3 + 2 - 0 = 5 `
it is boren `_(2)B^(10)`
