Outermost electron subshell configurations I: 5s2 5p5 F: 2s2 2p5 The molecular formula for iodine fluoride/ iodine heptafluoride/ iodine (VII) fluoride's IF7. As the outershell electrons of I are far away from the nucleus, and also that it's in the later periods; it can undergo sp3d3 hybridization as the difference between the energy level of the d-subshell and the p-subshell is small. I: 5s2 5p5 becomes: I: 5s1 5p1 5p1 5p1 5d1 5d1 5d1 The electrons are promoted to the 5d orbitals. Each fluorine atom then forms a single covalent bond with each of the lone electrons of the excited iodine.
