Write four characteristic properties of p- block elements

Explanation

### Step-by-Step Solution:

1. **Definition of p-block Elements**:
- The p-block elements are found in groups 13 to 18 of the periodic table. They include a diverse range of elements, including metals, metalloids, and non-metals.

2. **Characteristic Property 1 - Metallic and Non-metallic Character**:
- The metallic character of p-block elements increases as you move down a group. For example, elements like lead (Pb) exhibit more metallic characteristics than elements like boron (B) which is at the top of the group.
- Conversely, the non-metallic character increases as you move from left to right across a period. For instance, elements like fluorine (F) are highly non-metallic compared to elements like aluminum (Al).
