An electron in the first shell will have ________ stability and _______ energy than an electron in the third shell.

Explanation

To answer the question, "An electron in the first shell will have ________ stability and _______ energy than an electron in the third shell," we need to analyze the concepts of stability and energy in relation to electron shells.

### Step-by-Step Solution:

1. **Understanding Electron Shells**:
- Electrons occupy different energy levels or shells around the nucleus of an atom. The first shell (n=1) is closest to the nucleus, while the third shell (n=3) is further away.

2. **Stability of Electrons**:
