Which of the following is the correct electronic formula of chlorine molecule

Options

A. `overset(..)underset(..)(":Cl:")overset(..)underset(..)("Cl:")`
B. `overset(..)underset(..)(":"Cl^(-)":"):overset(..)underset(..)(Cl^(+)":")`
C. `overset(..)(":Cl:")overset(..)("Cl:")`
D. `overset(..)(":Cl:") overset(..)(":Cl:")`

Answer

A

Explanation

`:overset(..)underset(..)(Cl)..overset(..)underset(..)("Cl:")` is the correct electronic formula of `Cl_(2)` molecules because each chlorine has 7 electrons in its valence shell.
