Nucleus: Practice Problem & Solution

Assertion (A): Electron capture occurs more often than positron emission in heavy elements. Reason (R): Heavy elements exhibit radioactivity.

Both (A) & (R) are true and the (R) is the correct explanation of the (A)

Both (A) & (R) are true but the (R) is not the correct explanation of the (A)

(A) is true but (R) is false

Both (A) and (R) are false

Solution Explained:

To solve this problem, we apply the core principles of Nucleus. Understanding the underlying formula is key to arriving at the correct answer below:

In heavy nuclei, electron capture is favored over positron emission. So (A) is true. Heavy elements are generally unstable and radioactive. So (R) is true. However, (R) does not explain the preference for electron capture.
