(a)

Answer to Problem 10PE
Type of emission that occurs in transition from
Explanation of Solution
Skeleton equation for transition from
Since this transition cause no change in
(b)
Interpretation:
Type of emissions occurs in transition from
Concept Introduction:
Refer to part (a).
(b)

Answer to Problem 10PE
Type of emissions occurs in transition from
Explanation of Solution
Skeleton equation for transition from
Since transition causes loss in mass number by 4 and in atomic number by 2 hence 1 alpha particle is lost in this transition. Therefore alpha emission is taken place in this transition.
Hence resultant nuclear equation for alpha emission of
Skeleton equation for transition from
Since this transition causes atomic number to increase by 1 thus this transition is called beta emission. Resultant nuclear equation for beta emission of

Answer to Problem 10PE
Type of emissions occurs in transition from
Explanation of Solution
Skeleton equation for transition from
Since transition causes loss in mass number by 4 and in atomic number by 2 hence 1 alpha particle is lost in this transition. Therefore alpha emission is taken place in this transition.
Hence resultant nuclear equation for alpha emission of
Skeleton equation for transition from
Since this transition cause no change in atomic number as well as in mass number thus this transition is gramma emission. Resultant nuclear equation for gamma emission of
