Mass defect in the nuclear reactions may...

Mass defect in the nuclear reactions may be expressed in terms of the atomic masses of the parent and daughter neucliders in place of their nuclear masses.
The mass defect of nuclear reaction : `._(4)Be^(10)rarr ._(5)B^(10)+ e^(-)` is

A

`Delta m="At. mass of " ._(4)Be^(10)-"At. mass of " _(5)B^(10)`

B

`Delta m="At. mass of " ._(4)Be^(10)-"At. mass of " _(5)B^(10)` -mass of one electron

C

`Delta m="At. mass of " ._(4)Be^(10)-"At. mass of " _(5)B^(10)` + mass of one electron

D

`Delta m="At. mass of " ._(4)Be^(10)-"At. mass of " _(5)B^(10)` - mass of two electrons

Text Solution

Verified by Experts

The correct Answer is:
A
Nuclear reaction `._(4)B^(10) rarr . _(5)B ^(10)+ e^(-)`
Mass defect `=(4m_(p)+6m_(N))-[(5m_(p)+5m_(N))+m_(e)] `
`=(4m_(p)+6m_(N))-[(5m_(p)+5m_(N))+m_(e)] +4m_(e)-4m_(e)`
`=(4m_(p)+6m_(N)+4m_(e))-[5m_(p)+5m_(N)+5m_(e)]`
`="At mass of" ._(4)Be^(10)-"At. mass of " ._(5)B^(10)`
