Lewis Formula for Chlorine (Cl₂)

What is the correct Lewis formula for chlorine (Cl₂)?

1. :CI-CI:
2. :CH-CH:
3. :CIECI:
4. CI=CL
5. EE
6. HE
7. CI-CI
8. CI-CH

Answer:

The correct Lewis formula for chlorine (Cl₂) is CI-CL.

The correct Lewis formula for chlorine (Cl₂) is CI-CL. The Lewis formula represents the arrangement of atoms and electrons in a molecule. In this case, the Cl atoms are connected by a single bond (-) to form a Cl-Cl molecule.

In a Lewis formula, each line represents a shared pair of electrons. The chlorine molecule consists of two chlorine atoms (Cl) sharing one pair of electrons to form a stable Cl-Cl molecule.

This Lewis formula illustrates the covalent bond between the two chlorine atoms, where each Cl atom contributes one electron to the shared pair. This sharing of electrons allows both chlorine atoms to achieve a full outer electron shell, making the molecule more stable.

Understanding the Lewis formula for different molecules is essential in chemistry to visualize the arrangement of atoms and electrons in a compound. It helps in predicting the chemical behavior and properties of the substances.
