Use Lewis symbols to show electron transfer between the following atoms to form cations and anions: (a) `K` and `O` and ( b) `Al` and `N`.

Explanation

To solve the question of showing electron transfer between the specified atoms using Lewis symbols, we will break it down into two parts: (a) the interaction between potassium (K) and oxygen (O), and (b) the interaction between aluminum (Al) and nitrogen (N).

### Part (a): Electron Transfer between Potassium (K) and Oxygen (O)

1. **Draw the Lewis Symbols:**
- Potassium (K) has 1 electron in its valence shell. The Lewis symbol for potassium is represented as:
\[
\text{K} \rightarrow \cdot
