The elements of one short period of the periodic table are given below in order from left to right:
Li Be B C O F Ne
Place the three elements fluorine, beryllium and nitrogen in the order of increasing electronegativity.

Explanation

To solve the problem of arranging fluorine, beryllium, and nitrogen in the order of increasing electronegativity, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Electronegativity**: Electronegativity is the ability of an atom to attract shared electrons in a chemical bond. Generally, electronegativity increases across a period in the periodic table.

2. **Identify the Elements**: The elements we need to consider are:
- Beryllium (Be)
