Step 1:
I'll solve this problem step by step, following the specified LaTeX and formatting guidelines:

Step 2:
: Understand the Molecular Structure

- Cl₂ is a diatomic molecule composed of two chlorine atoms - Both chlorine atoms are identical - We need to analyze the bond and overall molecular geometry

Step 3:
: Electronegativity Consideration

- Chlorine has an electronegativity of $$2.96$$ on the Pauling scale
- When two identical atoms bond, they have the same electronegativity

Step 4:
: Electron Distribution Analysis

- Since both chlorine atoms have the same electronegativity, the electrons are shared equally - This means the electron density is symmetrically distributed along the bond - No charge separation occurs between the atoms

Step 5:
: Molecular Polarity Determination

- Equal electron sharing means no permanent dipole moment exists - The molecule has a linear symmetrical structure - Symmetry prevents any net separation of charge

Final Answer

Key Reasoning: Identical atoms with equal electronegativity create a symmetrical electron distribution, resulting in no net dipole moment.
