You are mostly correct.

The diatomic F2 is not called fluoride. This is the elemental form and it is called fluorine (gas), and it is a covalent bond between the two atoms. Similiarly, Two chlorine atoms covalently bonded is called chlorine (gas). Generally the suffix "ide" is reserved for the anion of the elemental form and can in most situations be thought of as in an ionic bond with a respective cation, such as hydrogen, sodium, or calcium. (There are exceptions, particularly with chlorine compounds which were discovered and named long before modern nomenclature.)

I'm only nitoicking to help clear up some of the widespread confusion people have about chemistry.
