What is the effect on neutron to proton ratio in a nucleus when (i) an electron, (ii) a positron is emitted?

Explanation

To solve the question regarding the effect on the neutron to proton ratio in a nucleus when (i) an electron is emitted and (ii) a positron is emitted, we can break it down step by step.

### Step-by-Step Solution:

1. **Understanding Electron Emission (Beta Decay)**:
- When an electron is emitted from the nucleus, this process is known as beta decay. In this process, a neutron is transformed into a proton.
- The reaction can be represented as:
\[
