In Cl
, the 2 is a subscript because it indicates there are 2 of the same elements. The Lewis structure would display it as Cl-Cl.
On the other hand, a superscript would indicate a specific charge.

or N, they both show that there are 2 of the same elements.
If the subscript is outside a parenthesis such as 
it indicates there are 2 
molecules.
Nitrogen is 5 valence electrons
oxygen is 6 valence electrons
fluorine is 7 electrons
