CsF is the bond between an alkali salt and a non-metal, and in this case a halogen. The reason for the bond is because they complete the valance electron (the outer electrons) of each other. Cs, when ionized, is Cs+. F is F-. The bond between two ions is, consequently, and ionic bond. OF2, however, is covalent because it is composed of non-metals. The Oxygen atoms, nor the Fluorine atoms were ionized (changed into 2+ or - respectively) before they were combined. In order to bind, they have to form a covalent bond, where the electrons also complete each other's shells. However, the force that keeps them together is immensely stronger than an ionic bond. Long story short - metal to non-metal - ionic
non-metal to non-metal - covalent the rest are detailed and not necessary for your question
OF2 is covalent.
No, OF2 is covalent
It is covalent, as are nearly all compounds consisting of only nonmetals.
OF2 is covalent. Both elements O and F are nonmetals. They would both form negative ions which would not attract each other.

OF2 is oxygen difluoride, a very powerful oxidizer.
As I originally stated in my original answer, the bonds in a molecule of OF2 are covalent. The electronegativity difference between them, according to the Pauling values is 0.54, which indicates a slightly polar covalent bond, in which Fluorine has the higher electronegativity value.
This compound is HBr.
Based on it's electronegative difference the kind of bond present in the compound OF2 is a Polar covalent bond.
Without the lone pairs of electrons, it would be F -- O -- F
The bond between O and F would be a covalent bond (dative/coordinate), if in fact OF existed. More likely it would exist as OF2 (still covalent bonds).
The words "covalent" and "ionic" refer to bonds between atoms, and not atoms themselves. If you are referring to O2 and F2, the forms in which we find oxygen and fluorine, respectively, then the bond between the two oxygens is considered to be non-polar and covalent. The same can be said of the bond between the two fluorine atoms in F2. If you are referring to the bonds in the compound formed by oxygen and fluorine, you must first identify that compound. It is OF2, and is named "fluorine oxide". The bonds between the oxygen and fluorine in fluorine oxide are slightly polar and covalent. The determining property is "electronegativity", which you should look up and review. By convention, when the electronegativity difference between atoms is: < about 0.4, the bond between them is non-polar and covalent between about 0.4 - 1.7, then bond between them is polar and covalent > 1.7, then bond between them is ionic.
