- The repulsion between the nonbonding pairs of electrons of two fluorine atoms is large
- The ionization energy of the fluorine atom is very low
- The length of the F-F bond much larger than the bond lengths in other halogen molecules
- The F-F bond distance is small and hence the internuclear repulsion between the two F atoms is very low.
