Short out the most and the least electronegative atoms among the following:
CI, Na, O, N, S, F, Cs

Explanation

To determine the most and least electronegative atoms among the given elements (Cl, Na, O, N, S, F, Cs), we will follow these steps:

### Step 1: Understand Electronegativity Trends
Electronegativity is the ability of an atom to attract electrons in a chemical bond. The trends in electronegativity on the periodic table are as follows:
- **Increases from left to right** across a period.
- **Decreases from top to bottom** within a group.

### Step 2: Identify the Position of Each Element
