Question:
F and F combine, Cl and Cl combine; what about F and Cl combining?


Replies:
Yes. There are a whole class of compounds involving the halogens. In this case two Cl/F interhalogens are known: ClF and ClF3, due to electronegativity of the fluorine. In the case of iodine and fluorine, IF, IF5, and even IF7 are all known. as are ICl and ICl3. As you might expect, the interhalogens are rather nasty to handle.

Vince Calder


Sure.

Any atom that makes simple covalent bonds, can usually make them with any other such atom. ClF is a stable gas molecule.

(There is also ClF3, which is not so simple.)
