Diagram:
Cl + Cl --> Cl:Cl
(Electron sharing)
Electronic Configurations:
Before bonding: Cl has 17 electrons (2, 8, 7).
After bonding: Each Cl atom effectively has 8 electrons in its valence shell (2, 8, 8). This is the same electron configuration as Argon (Ar), a noble gas. The sharing of a pair of electrons allows each chlorine atom to achieve a stable octet, mimicking the electron configuration of a noble gas.
