Lewis Structure of ONF

Why does O form a double bond with N while F doesn't?

Fluorine has 7 valence electrons so it only needs one more to complete its octet (also note that F is in period 2 and only elements in period 3 or higher can have an expanded valence shell since those elements have d-orbitals). Thus, F will form only single bonds. O needs 2 electrons to complete its octet and will therefore make up to a double bond. N needs 3 electrons to complete its shell and can therefore form up to a triple bond. However, since O only needs two electrons to complete its shell N can only share a double bond with O.
