Give reasons for the following:
Ionization potential of the element increases across a period.

Explanation

To explain why the ionization potential of an element increases across a period, we can break down the reasoning into several key points:

### Step-by-Step Solution:

1. **Understanding Ionization Potential**:
Ionization potential (or ionization energy) is the amount of energy required to remove the most loosely bound electron from an isolated gaseous atom.

2. **Atomic Size Across a Period**:
