Statement - I: If a nucleus may undergo positron decay as well as K-capture, the amount of
energy released in positron decay is more than that in K-capture.
Statement - II: The loss in K-capture is equal to the difference in atomic masses of parent
nucleus and the daughter nucleus but in positron decay, additional mass loss equal to the
mass of two electrons also occur.
energy released in positron decay is more than that in K-capture.
Statement - II: The loss in K-capture is equal to the difference in atomic masses of parent
nucleus and the daughter nucleus but in positron decay, additional mass loss equal to the
mass of two electrons also occur.
View answer and explanation
Correct option: A
If both Statement-I and Statement-II are true, and Statement-II is the correct
explanation of Statement-I
explanation of Statement-I
Option A is correct because both statements are true, and Statement II correctly explains why the energy released in positron decay is more than in K-capture.
